Question

A car of mass 1200 kg.what must be the force between the car and road if the car is to be stopped with a negative acceleration of 2ms^-2​

Answer 1

Answer:

m=1200kg

a=2 m/s^2

F=m*a

F=1200*2=2400N(negative)

Answer 2

Answer:

Since,

F=ma

=1200 x (-2)

=-2400N

So the force applied by the friction=-2400N
