Question

A 10 kg block experiences a net force in the opposite direction of its velocity for 1 s. Its velocity decreases by14 m/s. What is the magnitude of the net force? Calculate answer to one decimal.

Answer 1

Answer:

140 N

Explanation:

Impulse = change in momentum

J = Δp

FΔt = mΔv

F (1 s) = (10 kg) (14 m/s)

F = 140 N
