Problema Solution
An automobile is traveling at a velocity of 60 km/hr. It accelerates uniformly to a velocity of 100 km/hr during 8 minutes. What was the rate of acceleration?
Answer provided by our tutors
8 minutes = 8/60 hours
100 - 60 = 40
40 km/hr over a period of 8/60 hours:
40/(8/60) = 300.0
the rate of acceleration is 300 km/hr^2
