Micah knows that a car had a change in velocity of 15 m/s. to determine acceleration, micah also needs the of the total trip in seconds.

time

Explanation:

Acceleration is defined as the variation of Velocity (or change in velocity) in time :  

In the case of the car, Micah already knows the value of , and the needed value to completely find the acceleration is time in seconds, because the change in velocity is given in units of .

Hence:

Micah also needs the time of the total trip in seconds.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
