A car is moving with a velocity of 10 m/s. Suddenly driver sees a child at a distance of 30 m and he applies the brakes, it produced a uniform retardation in car and car stops in 5 second. Find (mass of car=1000 kg) <br> the stopping distance of car <br> will the car hit the child <br> the retardation in car <br> resistive force on car

Four cars are moving along a straight road in the same direction. Velocity of car 1 is `10 m//s`. It was found that distance between car 1 and 2 is decreasing at a rate of `2 m//s`, whereas driver in car 4 observed that he was nearing car 2 at a speed of `8 m//s`. The gap between car 2 and 3 is decreasing at a rate of `3 m//s`. <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/IJA_PHY_V01_C02_E01_031_Q01.png" width="80%"> <br> (a) `t = 0`, after how much time t0 will the driver of car 2 see for the first time, that another car overtakes him? <br> (b) Which car will be first to overtake car 1?

Car A moving along a straight horizontal road with a velocity 60 `"k.m"^(-1)` is followed by car B moving with a velocity 70 `"km.h"^(-1)`. When car B is at a distance 2.5 km from car A car B applies a retardation of 20 `"km.h"^(-2)`. Where and when will the two cars meet?
