Question

A 100N force is applied to a 20kg object that is initially at rest. If the force is applied for 0.5s, what is the final velocity? a. 1000 m/s b. 10 m/s c. 2.5 m/s d. 25 m/s

Answer 1

b. 10 m/s

Step-by-step explanation:

force = mass x acceleration
100 = 20 x a
a = 5

acceleration = (final velocity - initial velocity) ÷ time

5 = (x - 0) ÷ 0.5
10 = x
