Question

A car on a straight level road, starts from rest and accelerates to a speed of 1,846 ft/'s in 49 seconds. What is the car's average acceleration in ft/s??

Answer 1

Here,

initial speed , u = 0 m/s

final speed, v = 1846 ft/s

t = 49 s

average acceleration = (v - u)/t

average acceleration = (1846 - 0)/49

average acceleration = 37.7 ft/s^2

the car's average acceleration is 37.7 ft/s^2
