Good Day

Problem:

a skateboard from rest until it accelerates at a rate of 3.5 m/s². How fast is the skateboard after travelling 8.5 m ?

Given data:

a (acceleration) = 3.5 m/s²

d (distance) = 8.5 m

Vi (initial velocity) = from rest (0 m/s)

Vf (final velocity) = ? unknown

Solution:

We can use the formula, Vf = √Vi² + 2ad

Vf = √Vi² + 2ad

    = √(0 m/s)² + 2 (3.5 m/s²) × 8.5 m

    = √7 m/s² × 8.5 m

    = √ 59.5 m²/s²

    = 7.71 m/s

Answer:

The final velocity is 7.71 m/s
