Question

A car starts from rest and accelerates along a straight line path in one minute. It finally attains a velocity of 40 meters/second. What is the car's average acceleration? A. 1.5 meters/second^2 B. 1.5 meters/second C. 0.66 meters/second^2 D. 0.66 meters/second

Answer 1

Speed = (acceleration) x (time). .. Divide each side by 'time'. ... Acceleration = (speed) / (time). .. That's (40 m/s) / (60 sec) = 2/3 m/sec^2 .
