Question

A golf ball accelerates on a tee at 15 m/s², changing its velocity from 0 m/s to 50 m/s down the fairway. How long did it take the golf ball to accelerate?

A) 2 seconds
B) 3 seconds
C) 4 seconds
D) 5 seconds

Answer 1

The golf ball took approximately 3 seconds to accelerate.

Step-by-step explanation:

To find the time it takes for the golf ball to accelerate, we can use the equation:

final velocity = initial velocity + (acceleration * time)

Since the initial velocity is 0 m/s and the final velocity is 50 m/s, we can rearrange the equation to solve for time:

time = (final velocity - initial velocity) / acceleration

Plugging in the values, we get:

time = (50 m/s - 0 m/s) / 15 m/s² = 3.33 seconds

Therefore, it took the golf ball approximately 3 seconds to accelerate.
