Calculate how much his potential energy increases in one second. Use the formula PE = mgh (mass x gravity x height), mass in kg, gravity = 9.8 (meters per second squared), convert height to meters. Result will be in Joules. The standard unit of power, Watts, means Joules / second.

How can you calculate the rockets average velocity?
You calculate a rockets average velocity the same way you calculate the average velocity of anything else, a car, a running dog, or a stick floating on a stream. Velocity equals distance divided by time. It does not matter if your rocket traveled five thousand kilometers in one hour or if your car traveled 30 miles in one hour even if it stopped for gas along the way, you use the same formula.
What is the average speed of man running?
The original answer is misleading 15MPH is world class. Sprinting up to 100 yards - record is ~23 MPH - average ~14 Running up to a mile /1600 meters record is ~16MPH - average ~10MPH Marathon distance record ~26 Mile/42 Km is ~13MPH/21KmPH reasonable 9MPH 14KmPH (NY marathon qualification time) For figuring out how fast you can get between two points these are probably better values as they assume you can actually not spend too much time recovering. The Average walking speed is 3-4 MPH 5-6 KmPH or about 100 yards/meters per minute Running speed sustained is about twice that 8 MPH, 12 KmPH or 200 yards/meters per minute.
Select the situation below that would produce an average velocity of zero.?

How do you know that there is energy in an electric motor?
If there is energy in an electric motor (electricity is being supplied to it). it will be turing/running. When there is no energy in it (being supplied to it) it will stop.

Do running headlights drain the car battery?
No. The power to illuminate the Daytime Running Lights (DRL's) is supplied by the alternator, and does not have to be supplied by the battery. Once a vehicle is started and the engine is running you could remove the battery from the car entirely and everything requiring current would still operate.
