In a vacuum, if a 0.045 kg golf ball is accelerated upward at 2.5 m/s2 by a hair dryer, how much force is required to accelerate the ball?

F = 0.553 N

Explanation:

Given that,

Mass of a golf ball, m = 0.045 kg

Acceleration in upward direction, a = 2.5 m/s²

We need to find the force is required to accelerate the ball. Let the force be F. Using the second law of motion as follows :

F = m(a+g)

So,

F = 0.045 (2.5+9.8)

F = 0.553 N

So, the force required to accelerate the ball is 0.553 N.
