Question

Natalie accelerates her skateboard along a straight path from 0 m/s to +4.0 m/s in 2.5 s. Find her average

acceleration.

Answer 1

`a=1.6\ m/s^2`

Step-by-step explanation:

Given that,

Initial speed, u = 0 m/s

Final speed, v = 4 m/s

Time, t = 2.5 s

We need to find the average acceleration of Natalie. We know that average acceleration is equal to the change in speed per unit time. So,

`a=(v-u)/(t)\\\\a=(4-0)/(2.5)\\\\a=1.6\ m/s^2`

So, her average acceleration is
`1.6\ m/s^2`.
