A car is travelling on straight level road with a uniform speed of 60kmph it is followed by another car B which is moving with speed of 70kmph when the distance between them is 2.5km the car Back is given a deceleration of 20km/h2 after what distance of time B will catch up with A

Question

Khimraj · Answer

s2 = ut + ½*a*t 2 = 70t + ½*(-20)*t 2 = 70t -10t 2 s1 = 60t s2 – s1 = 2.5 70t – 10t 2 -60t = 2.5 10t 2 -10t + 2.5 = 0 so t = ½ h putting this in s2 s2 = 32.5km Hope it clears.
