Question

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? thanx for answering :)

Answer 1

Question A:
Change in velocity = Acceleration * time

Make sure time is in seconds.

Question B:
Final speed = initial speed + (acceleration * time)

Once again make sure all units are in metres, seconds, or some conjunction of the two.
ok :)
