Answer:
Average force exerted on car = 250,000 N or 250 KN
Explanation:
Given:
Initial speed u = 20 m/s
Final speed v = 0 m/s
Total distance covered = 1.2 m
Find:
Average force exerted on car
Computation:
v² = u² + 2as
0² = 20² + 2(a)(1.2)
a = -166.67 m/s² or 166.67 m/s²
Average force exerted on car = Ma
Average force exerted on car = (1,500)(166.67)
Average force exerted on car = 250,000 N or 250 KN
