A car travels with a speed of 20m/s to east.at t=0,the driver sees a bus coming 100m behind with a speed of 25m/s breaks immediately and decelerates uniformly for 2s.After a time t after applying breaks,the bus passes the car and car travels with the same speed which it had. (Take the speed of car after deceleration as u)
1.write an expression for the deceleration of the car in terms of u and t
2.when the bus passes the car,write an expression for the distance travelled by car
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
