Question

A car is moving with a speed of 54 km/h is brought to rest while covering a distance of 150 m. If mass of car is 600 kg, find the retarding force on the car.​

Answer 1

Answer:

U is 15 m/s

V is 0m/s because at last the object comes at rest.

S is 3/20km so we convert it into m/s .on converting it is 3/20×1000 m per second .

using v^2 - u^2=2as

a=3/4 m/s^2( by calculations )

using F=M×A

F=600Kg × 3/4m/s^2

F=450N
