What are trực tiếp bóng đá k+ 15-minute question papers for 10th-grade Physics in Vietnam?
trực tiếp bóng đá k+ 15-minute question paper for 10th-grade Physics is a type of short test, often used to assess trực tiếp bóng đá k+ knowledge and skills of students within a short period of time (approximately 15 minutes).
Students can refer to trực tiếp bóng đá k+ following 15-minute question papers for10th-gradePhysics:
Question 1:What is uniform straight-line motion?
Question 2:What coordinates are used to determine trực tiếp bóng đá k+ position of trực tiếp bóng đá k+ maritime patrol vessel 8001 between trực tiếp bóng đá k+ ocean?
Question 3:A car departs from Giap Bat bus station, accelerating uniformly in a straight line, and reaches a speed of 5 m/s after traveling 25m. Calculate trực tiếp bóng đá k+ car's acceleration and trực tiếp bóng đá k+ speed it reaches after traveling an additional 25m?
Question 4:Around 2:30 PM on September 6, 2016, at National Highway 20 passing through Dam Ri commune-level town (Da Huoai, Lam Dong), a passenger bus carrying 30 people showed signs of brake failure. Upon discovering trực tiếp bóng đá k+ incident, driver Phan Van Bac skillfully maneuvered his truck and signaled for trực tiếp bóng đá k+ bus to make contact with trực tiếp bóng đá k+ rear of his vehicle, guiding it down a 500-meter slope on Bao Loc Pass until both vehicles came to a safe stop at trực tiếp bóng đá k+ bottom of trực tiếp bóng đá k+ slope. Assuming trực tiếp bóng đá k+ two vehicles were traveling at 54km/h when they made contact at trực tiếp bóng đá k+ top of trực tiếp bóng đá k+ slope, consider them to be in uniform deceleration until they stopped.
a) Establish trực tiếp bóng đá k+ motion equation of trực tiếp bóng đá k+ two vehicles when they adhered to each other and moved down trực tiếp bóng đá k+ slope.
b) Write trực tiếp bóng đá k+ velocity formula of trực tiếp bóng đá k+ two vehicles when they adhered to each other and moved down trực tiếp bóng đá k+ slope.
Solution:
Question 1:What is uniform straight-line motion?
Uniform straight-line motion is a type of motion where trực tiếp bóng đá k+ trajectory is a straight line and trực tiếp bóng đá k+ velocity remains constant over time. That is, trực tiếp bóng đá k+ object moves along a straight line and covers equal distances in equal intervals of time.
Question 2:What coordinates are used to determine trực tiếp bóng đá k+ position of trực tiếp bóng đá k+ maritime patrol vessel 8001 between trực tiếp bóng đá k+ ocean?
To determine trực tiếp bóng đá k+ position of an object on Earth, especially at sea, longitude and latitude coordinate systems are typically used.
Longitude is trực tiếp bóng đá k+ angle between trực tiếp bóng đá k+ meridian that passes through that point and trực tiếp bóng đá k+ prime meridian (Greenwich meridian).
Latitude is trực tiếp bóng đá k+ angle between trực tiếp bóng đá k+ equator and trực tiếp bóng đá k+ line perpendicular to trực tiếp bóng đá k+ Earth's surface passing through that point.
Additionally, other coordinate systems such as UTM, Gauss-Kruger are used for more detailed positioning.
Question 3:
Summary:
v₀ = 0 m/s (trực tiếp bóng đá k+ car starts from rest)
s₁ = 25 m
v₁ = 5 m/s
Find: a, v₂ (speed after traveling an additional 25m)
Solution:
Acceleration a: Apply trực tiếp bóng đá k+ formula relating velocity, acceleration, and distance: v₁² - v₀² = 2as₁ = a = (v₁² - v₀²) / (2s₁) = (5² - 0²) / (2*25) = 0.5 m/s²
Velocity v₂ after an additional 25m: Total distance: s₂ = s₁ + 25 = 50 m Apply a similar formula: v₂² - v₀² = 2as₂ = v₂ = √(2as₂) = √(20.5*50) = 7.07 m/s
Answer:
Acceleration a = 0.5 m/s²
Velocity v₂ = 7.07 m/s
Question 4:
Summary:
v₀ = 54 km/h = 15 m/s (initial speed of trực tiếp bóng đá k+ two vehicles when they adhered to each other)
s = 500 m (distance traveled by trực tiếp bóng đá k+ two vehicles until they stopped)
v = 0 m/s (final speed when trực tiếp bóng đá k+ two vehicles stopped)
Solution:
a) Motion equation of trực tiếp bóng đá k+ two vehicles: Choose trực tiếp bóng đá k+ origin at trực tiếp bóng đá k+ top of trực tiếp bóng đá k+ slope, positive direction as trực tiếp bóng đá k+ direction of trực tiếp bóng đá k+ vehicles' motion, and time zero as when trực tiếp bóng đá k+ two vehicles start decelerating. Motion equation: x = x₀ + v₀t + 0.5at² With x₀ = 0 (since trực tiếp bóng đá k+ origin is at trực tiếp bóng đá k+ top of trực tiếp bóng đá k+ slope), v₀ = 15 m/s. To find a, use trực tiếp bóng đá k+ formula v² - v₀² = 2as = a = -v₀² / (2s) = -15² / (2*500) = -0.225 m/s² So trực tiếp bóng đá k+ motion equation is: x = 15t - 0.1125t²
b) Velocity formula: v = v₀ + at = 15 - 0.225t
Note:
trực tiếp bóng đá k+ negative sign of acceleration indicates trực tiếp bóng đá k+ vehicles are decelerating uniformly.
trực tiếp bóng đá k+ motion equation and velocity formula above are only valid for trực tiếp bóng đá k+ scenario where trực tiếp bóng đá k+ two vehicles adhered to each other and decelerated uniformly until they stopped completely.
