Find the acceleration of a hamster when it increases its velocity from rest to 8.0 m/s in 3.0 s.

Acceleration is the change in velocity divided by time.

We can find acceleration a, by the following formula

a=v-u/t

where,

v is the final velocity (in this question v=8.0 m/s)

u is the initial velocity (since the hamster starts from rest, u=0)

t is the time taken (i, e 3.0 second)

now by applying the formula we have,

a = 8.0 - 0 / 3

= 8 / 3

= 2.65 m/s ²

The acceleration is 2.65 meters per second squared
