Question

A golf ball starts with a speed of 2 m/s and slows at a constant rate of 0.5 m/s2, what is its velocity after 2 s?​

Answer 1

3m/s

Step-by-step explanation:

Given parameters:

Initial speed = 2m/s

Acceleration = 0.5m/s²

Time = 2s

Unknown:

Final speed = ?

Solution:

To solve this problem, we apply the right motion equation;

V = U + at

V is the final speed

U is the initial speed

a is the acceleration

t is the time

V = 2 + (2 x 0.5)

V = 2 + 1

V = 3m/s
