A car moving at 10 m/s speeds up with a constant acceleration of 2 m/s² for 3 s. Find its final speed v.
Kinematics worksheet with answers
A car moving at 0 m/s speeds up with a constant acceleration of 0.5 m/s² for 3 s. How far does it travel in that time? Find s.
A car driving at 54 km/h brakes with a constant deceleration of 6.5 m/s² until it stops. Find the braking distance s.
A car driving at 36 km/h brakes with a constant deceleration of 8 m/s² until it stops. How long does braking take? Find t.
A model rocket is launched straight up from rest. Its engine gives it a constant upward acceleration of 34 m/s² for 2 s, after which the engine stops and the rocket moves freely. Ignore air resistance and use g = 9.81 m/s². How long after launch does it hit the ground? Find t.
Ball A is dropped from rest from a height of 55 m. At the same instant ball B is thrown straight up from the ground directly below at 22 m/s. Ignore air resistance and use g = 9.81 m/s². When do the balls meet? Find t.
Answer key
- 1. v = 16 m/s
- 2. s = 2.25 m
- 3. s = 17.31 m
- 4. t = 1.25 s
- 5. t = 16.8 s
- 6. t = 2.5 s
