1
A car accelerates uniformly from rest to a velocity of 20 m/s in 5 seconds. What is its acceleration?
2
An object is thrown vertically upwards with an initial velocity of 15 m/s. Neglecting air resistance, what is the maximum height reached by the object? (Assume g = 9.8 m/s²)
3
A train travels at a constant velocity of 30 m/s for 20 seconds, then decelerates uniformly at 2 m/s² until it stops. What is the total distance traveled by the train?
4
A particle moves along the x-axis with a velocity given by v(t) = 3t² - 6t + 4. What is the acceleration of the particle at t = 2 seconds?
5
A ball is dropped from a height of 45 meters. Ignoring air resistance, what is the approximate time it takes for the ball to reach the ground? (Assume g = 9.8 m/s²)
6
An object moves with constant acceleration. Its initial velocity is 5 m/s and after 4 seconds its velocity is 17 m/s. What is the distance traveled during this time?
7
Two cars start at the same point and travel in the same direction along a straight road. Car A has a constant velocity of 40 m/s, and Car B starts from rest and accelerates uniformly at 2 m/s². After how many seconds will Car B overtake Car A?
8
A projectile is fired vertically upwards. At what point in its path does it have zero velocity and non-zero acceleration?
9
A body moves along a straight line such that its displacement is given by s = t³ - 6t² + 3t + 4 meters, where t is in seconds. Find the velocity of the body when its acceleration is zero.
10
An elevator is moving upwards with a constant acceleration of 2 m/s². A person inside the elevator drops a coin from a height of 2 meters above the floor. How long does it take for the coin to hit the floor? (Assume g = 9.8 m/s²)
