Suppose a treadmill has an average acceleration of 4.7 x 10^-3. a) how much does its speed change after five min? b )if the treadmill's initial speed is 1.7 m/s ,what will it's final speed be?

Explanation:

Given that,

Acceleration of the treadmill,

Time, t = 5 min = 300 s

Acceleration is given by :

(a) (v-u) is the change in speed.

So, the change in speed of the treadmill is 1.41 m/s.      

(b) Initial speed of the treadmill, u = 1.7 m/s

The final speed is given by using equation as :

v = 3.11 m/s

Hence, this is the required solution.

what was the answer?

the answer is a. at the equator
