Answer:
40000N
Explanation:
Given parameters:
Mass of the car = 1000kg
Velocity of the car = 20m/s
Time taken = 0.5s
Unknown:
Force on the car = ?
Solution:
According to Newtons second law of motion:
F = m a
F is the force
m is the mass
a is the acceleration
F = m
Change in velocity = 0 - 20 = -20m/s
F = 1000 x = -40000N
The force on the car is 40000N
