Motion in A Str...

The following figure gives the movement of an object. Select the correct statement from the given choices.

A body starts from rest and is uniformly accelerated for $$30s$$. The distance travelled in the first $$10s$$ is $$x_{ 1 }$$ next $$10s$$ is $$x_{ 2 }$$ and the last $$10s$$ is $$x_{ 3 }$$.Then $$x_{ 1 }:x_{ 2 }:x_{ 3 }$$  is the same as :-

A parachutist drops first freely from an aeroplane for 10 s and then his parachutist opens out. Now he descends with a net retardation of $$2.5ms^{-2}$$. If he bails out of the plane at a height of 2495 m and $$g = 10 ms^{-2}$$, his velocity on reaching the ground will be 

A person moves 30 m north and then 20 m towards east and finally $$30\sqrt { 2 } $$ m in south-west direction. The displacement of the person from the origin will be

The maximum velocity attained by the car is

The velocity of the body at any instant is

A point moves with uniform acceleration and $$v_1,v_2,$$ and $$v_3$$ denote the average velocities in the three successive intervals of time $$t_1,t_2,$$ and $$t_3$$. Which of the following relations is correct? 

The distance covered by the second body when they meet is

The velocity of the body at the end of 1 s from the start is

After what time will he be able to overtake the bus?
