Question 1
4 / -1

A car A is travelling on a straight level road with a uniform speed of 60 km/h. It is followed by another car B which is moving with a speed of 70 km/hr. When the distance between them is 2.5 km, the car B is given a deceleration of 20 km/hr². After how much time will B catch up with A

A
1 hr

B
1/2 hr

C
1/4 hr

D
1/8 hr

Solution

B
10 s

C
15 s

Solution
Question 6
4 / -1

A particle is moving in a straight line and passes through a point Owith a velocity of 6 ms^–1. The particle moves with a constant retardation of 2 ms^–2 for 4 s and there after moves with constant velocity. How long after leaving O does the particle return to O

B
8 s

C
Never

D
4 s

Solution
