A car is travelling at 30 m/s. If its velocity increases to 50 m/s while accelerating at the rate of 2.5 m/s$\displaystyle ^{2}$ find the time taken to reach that velocity.

The quantity which tells the distance an object travels in a certain time is called -

A stone dropped from the top of a tower reaches the ground with a velocity of 58.8 m/s in 6 seconds. Calculate the value of acceleration due to gravity.

If two bodies are moving with the same speed but in different directions they will have -

A boy cycles a distance of 640 m in 2 minutes and 40 seconds. What is the speed of the cycle?

The velocity of a bullet is reduced from $200\;\text{m/s}$ to $100\;\text{m/s}$ while travelling through a wooden block of thickness $10\;\text{cm}$. Assuming it to be uniform, the retardation will be:

A ball thrown vertically upwards with a velocity of 15 m/s reaches its highest point at 11.25 m in 1.5 sec. Find the total distance travelled by the ball and its position after 2 sec respectively. Take $g=10 \ m/s^2$

A runner running along a circular track at a constant speed has _______ velocity.

Can a moving object cover zero distance?

A body, initially at rest, starts moving with a constant acceleration $2 m{s}^{-2}$. Calculate the distance travelled in 5 s.
