What does the odometer of an automobile measure?

A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of $3.0\ ms^{-2}$ for $8\ s$. 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 rest?

If the displacement of an object is proportional to square to time, then the object moves with:

The table below shows the speed of a moving vehicle with respect to time.

An object is sliding down on an inclined plane. The velocity changes at a constant rate from 10 cm/s to 15 cm/s in 2 seconds. What is its acceleration?

Two stones are thrown vertically upwards simultaneously with their initial velocities $u_1$ and $u_2$ respectively. The heights reached by them would be in the ratio of 

A ball is gently dropped from a height of 20 m. If its velocity increases uniformly at the rate of $10 ms^{-2}$, with what velocity will it strike the ground and time after which it will it strike the ground?

An iron sphere of mass 10 kg is dropped from a height of 80 cm. If the downward acceleration of the sphere is $10 ms^{-2}$, calculate the momentum of the sphere when it just strikes the ground

Which of the following relations is correct?
