Question

What is the acceleration of an object if the velocity of am objects changes from 65 ms to 98 m/s during a time interval of 12 s?

Answer 1

Acceleration = (change in speed) / (time for the change)

Change in speed = (ending speed) minus (starting speed)

= (98 m/s) - (65 m/s) = 33 m/s

Acceleration = (33 m/s) / (12 sec) = 2.75 m/s²
