A ball is set in motion down a constant slope. At a certain point in its descent, the ball is rolling at 16 m/s and accelerates to 32 m/s in 8 seconds. How fast is the acceleration?

Question

Quizplus · Accepted Answer

Step 1: Find the acceleration Acceleration = change in velocity ÷ time taken The ball starts at 16 and accelerates to 32 m/s which makes the change in velocity: 24 m/s - 16 m/s= 16 m/s The ball took 8 seconds to reach the 24 m/s velocity so the time taken equals 8 s. Enter these numbers into the acceleration formula: acceleration = 16 m/s ÷ 8 s acceleration = 2 m/s²
