average force  is 138900 N

Explanation:

given data

speed = 50 km/h = 13.89 m/s

mass = 1500 kg

time = 0.15 s

to find out

average force

solution

we know initial velocity of car is positive

we will apply here equation to find force that is

Force x change in time that is equal to  mass x change in speed    1

so put here all value of mass, time and velocity in equation 1

Force x 0.15 =  1500 x ( -13.89)

force = 138900 N

so average force  is 138900 N
