Question

The balls velocity started at 20m/s and increased to 40 m/s in 3 seconds. What was the

Answer 1

Answer:

$a = \frac{20}{3} \frac{m}{s {}^{2} }$

Explanation:

The formula for velocity is:

$v = vo - a \times t$

Where

$vo$

is the ball's initial velocity.

solving for a:

$40 = 20 + a \times t \\ 20 = a \times t \\ 20 = 3a \\ a = \frac{20}{3}$
