Question

Car of mass 500 kg moving at a speed of 18 kilometre per hour is stopped by applying brakes in 10 second calculate the force applied by the brakes

Answer 1

Mass=500kg

Initial velocity=18×5/18=5m/s

Final velocity=0m/s

Time taken =10seconds

Force=m(v-u)/t

500(0-5) /10

500×(-5)/10

-2500/10=-250 N rate 5 star play hope it's helpful
