Motion Test - 5...

With what speed should a bus travel so that it can cover a distance of 10 km in 5 min?

A man runs $$20 \  km$$ in $$30 \ min.$$ What is his speed?

The displacement of a body starting from rest, and moving with an acceleration of $$1 \ { ms }^{ -2 }$$ at the end of 5 s is ____ m.

The ratio of the heights from which two bodies are dropped is 3 : 5 respectively. The ratio of their final velocities is

If a ball thrown vertically up attains a maximum height of $$80\ m,$$ its initial speed is $$\displaystyle ( g = { 10\ ms }^{ -2 } )$$.

The velocity of a retarding body changes from $$\displaystyle { 90\ ms }^{ -1 }$$ to $$36\ ms^{ -1 }$$ in $$9$$ seconds. Find the retardation of a body?

The final velocity of a body starting from rest and moving with an acceleration $$\displaystyle 2  \ { ms }^{ -2 }$$ and covering a distance of 10 m is _____ $$\displaystyle { ms }^{ -1 }$$.

Which of the following formulae is correct?

Calculate the distance travelled by a man walking at a speed of 5 km/hr in 36 minutes.

A car is travelling at a certain speed. Its final velocity reaches 40 m/s in 10 seconds accelerating at the rate of 2.5 m/s$$\displaystyle ^{2}$$. Find the initial velocity of the car.
