Question 6 • Mad 2017 Phy Sci B -33 SS

A ball has a mass of 140 g. What is the force needed to accelerate the ball at 25 m/s2? (Formula: F=ma)

Answer
A
3.5 N
B
115 N
C
165 N
D
4.5 N

Explanation

Use F = ma, first converting the mass to kilograms: 140 g = 0.140 kg. Then F = 0.140 × 25 = 3.5 N, so the force needed is 3.5 N, choice A.
