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
