Question

Calculate the speed (in m/s) of a skateboarder who accelerates from

rest for 3 seconds down a ramp at an acceleration of 5m/s2

​

Answer 1

Explanation:

Calculate the speed of a skateboarder who accelerates from rest for 3 seconds down a ramp at an acceleration of 5 m/s2. every second. After three seconds, speed will increase by "5 m/s/s x 3 s = 15 m/s

Answer 2

Given:

Acceleration of the skateboarder = 5 m/s²

Time period of the acceleration = 3 seconds

To find:

The velocity of the skateboarder.

Solution:

We know that the formula of acceleration is = velocity / time

Thus on re-arranging, the formula for velocity will be = acceleration × time.

On substituting the given values in the formula, we get:

velocity = 5 × 3 = 15 m/s

Thus, the velocity of the skateboarder will be 15 m/s.
