Answer:
30,000
Step-by-step explanation:
1)Find the force that causes the car to accelerate.
a = change in velocity/ change in time
a = 60/3 = 20 m/s^2
F = ma = (1500)(20)
F= 30000N
2) The car will not accelerate if its net force is 0. So if 30,000N of force is applied in the direction opposite of the displacement, then the car will not move.
