3A body accelerates uniformly from 10 m/s to 26 m/s over 4 s. Find its acceleration.

4A body with u = 3 m/s and a = 2 m/s² has velocity ___ m/s after 2 s.

5A body with u = 5 m/s and a = 2 m/s² has velocity ___ m/s after 6 s.

6A body accelerates uniformly from 6 m/s to 15 m/s over 3 s. Find its acceleration.

7A ball is thrown vertically upwards at 20 m/s. Find the maximum height reached. (g = 10 m/s²)

8A ball is thrown vertically upwards at 10 m/s. Find the maximum height reached. (g = 10 m/s²)

9A body thrown upward has zero velocity at the top.

10A car with initial velocity 0 m/s accelerates at 3 m/s² for 6 s. Find its final velocity.
