Suppose a treadmill has an average acceler- ation of 0.0046 m/s
How much does its speed change after 4.3
min?
Answer in units of m/s.

1.02  m/s

Explanation:

Speed change = (final speed) - (initial speed)

Final speed = (initial speed) + (acceleration) x (time)

So Speed change = (acceleration) x (time)

(4.3 min) x (60 sec /min) = 258 seconds

Speed change = (0.0046 m/s²) x (258 seconds)

Speed change = 1.02m/s
