Question

A baseball accelerates at 15m/s2, changing its velocity from 0m/s to 50 m/s down the way. How long did it take the baseball to accelerate?

Answer 1

3.33s

Step-by-step explanation:

Given parameters:

Acceleration = 15m/s²

Initial velocity = 0m/s

Final velocity = 50m/s

Unknown:

Time taken for the acceleration = ?

Solution:

To solve this problem, we must understand that acceleration is the rate of change of velocity with time.

Mathematically;

a =
`(v - u)/(t)`

a is the acceleration

v is the final velocity

u is the initial velocity

t is the time taken

So;

15 =
`(50 - 0)/(t)`

15t = 50

t = 3.33s
