Explanation:
Power = Energy / Time
When the velocity doubles the kinetic energy increases by a factor of 4.
So if the time is constant and the velocity doubles, then the power will increase to a factor of 4.
Answer:
The net force acting on that object must be 0
Explanation:
According to Newton's first law of motion, if there's no force acting on an object (or the net force is 0), that object will stay at the same speed. That object acceleration must also be 0.
Micah knows that a car had a change in velocity of 15 m/s.To determine acceleration ,Micah also needs the TIME of the total trip in seconds.
