A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of `3.0 ms ^(-2) ` for 8.0 s . How far does the boat travel during this time?

A car starts from rest and moves along the x-axis with constant acceleration 5 ms^(-2) for 8 seconds. If it then continues with constant velocity, what distance will the car cover in 12 seconds since it started from the rest ?

A motorcycle starts from rest. The uniformly accelerates at 1m//s^2 . Find the distance travelled in the 3rd second.

A bus starting from rest moves with a uniform acceleration of 0.1 ms^-2 for two minutes. The distance travelled.

A truck starts from rest and rolls down a hill with constant acceleration. It travels a distance of 400 m in 20 s. Find its acceleration. Find the force on it if its mass is 7 metric tonnes.
