Question

A rubber ball weighs 49 N. What is the acceleration of the ball if an upward force of 69 N is
applied?

Answer 1

Hint: The net force on the ball is
F = 69 - 49 = 20 N

The mass of the ball is
M = 49/g = 5.0 kg

The acceleration is a = F/M

Answer 2

4 meters / (seconds squared)

Answer 3

13.8
