Question

What force is needed to propel a 421-kg car with an acceleration of 3.77 m/s2?
1.12 x 106 N
8.95 x 10-3 N
4.40 x 103 N
1.59 x 103N

Answer 1

Answer:

The last one

Explanation:

F=ma

F=421×3.77=~1.59×10^3N

Answer 2

Answer:1.59 x 10^3 N

Explanation:

Force = Mass x Acceleration due to gravity.

F = 421 * 3.77 = 1.59 x 10^3 N
