A racing car has uniform acceleration of `4ms^(-2)`. What distance will it cover in 10 s after start?

A trolley, while going down an inclined plane has an acceleration of 2cm s^(-2) What will be its velocity 3 s after the start?

An electron moving with a velocity of 5 xx 10^(4)ms^(-1) enters into a uniform electirc field and acquires a uniform acceleration of 10^(4)ms^(-2) in the direction of its initial motion. Calculate the time in which the electron would acquire a velocity double of its initial velocity.

A man weighs 80 kg. He stands on a weighing scale in the lift, which is moving upward with a uniform acceleration of 5 ms^-2 what whould be the reading on the scale? (g = 10 m//s^2) .
