Given:

Velocity = 70 m/s

Time = 15 seconds

Determine the acceleration.

Formula for acceleration:

a = delta v / delta t

a = Change in Velocity/ Change in Time.

Solution:

Transpose the values of v and t to the formula for acceleration.

a = 70 m/s / 15 s

a = 4.667 m/s^2 

Final answer:

The acceleration of the car is 4.667 m/s^2
