Acar 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

The average acceleration of the car is given by:

where  is the initial velocity of the car,  is its final velocity and t is the time taken to attain the final speed. The car in the problem starts from rest, therefore its initial velocity is zero: . The final velocity is , while the time taken is

Therefore, the average acceleration of the car is

and the correct answer is C.

Scissors and a seesaw both cut things that’s the only comparison
