Find the total distance travelled.

A ball is initially moving with a velocity $$0.5 m{s}^{-1}$$. Its velocity decreases at a rate of $$0.05 m{s}^{-2}$$. How much time will it take to stop?

Find the distance which the car travels before the brakes are applied.

A particle starts to move in a straight line from a point with velocity $$10 m{s}^{-1}$$ and acceleration $$- 2.0 m{s}^{-2}$$. Find the position of the particle at $$t = 5 s$$

Larger the slope of a displacement-time graph

A train is moving with a velocity of $$90\ kmph$$. When brakes are applied, the retardation produced is $$0.5\ m{s}^{-2}$$. Find the velocity after $$10 s$$.

A train is moving with a velocity of $$90\  kmph$$. When brakes are applied, the retardation produced is $$0.5 m{s}^{-2}$$. Find the time taken by the train to come to rest.

If a displacement-time graph of an object is a straight line parallel to the time axis, the object is

A vehicle moving with a constant acceleration from $$A$$ to $$B$$ in a straight line $$AB$$, has velocities $$u$$ and $$v$$ at $$A$$ and $$B$$ respectively. $$C$$ is the mid point of $$AB$$. If time taken to travel from $$A$$ to $$C$$ is twice the time to travel from $$C$$ to $$B$$ then the velocity of the vehicle $$v$$ at $$B$$ is:

When a body moves in an uniform circular motion, changes in velocity and speed will be
