A train slows down uniformly from 16 m/s to 3 m/s in 16 s. How far does it travel in that time? Find s.
Kinematics worksheet with answers
A car moving at 12 m/s speeds up with a constant acceleration of 1.5 m/s² for 12 s. Find its final speed v.
A car speeding at a constant 18 m/s passes a police car standing still. At that moment the police car starts and accelerates uniformly at 5 m/s². How long does it take the police car to catch up? Find t.
A car driving at 72 km/h brakes with a constant deceleration of 6.5 m/s² until it stops. Find the braking distance s.
A ball is thrown straight up at 14 m/s from the edge of a roof 20 m above the ground. Ignore air resistance and use g = 9.81 m/s². Find the greatest height hmax above the ground.
A ball is thrown straight up at 12 m/s from the edge of a roof 20 m above the ground. Ignore air resistance and use g = 9.81 m/s². How long after the throw does it hit the ground? Find t.
Answer key
- 1. s = 152 m
- 2. v = 30 m/s
- 3. t = 7.2 s
- 4. s = 30.77 m
- 5. hmax = 29.99 m
- 6. t = 3.584 s
