Four and half
right around 220# but that is not the exact answer, it is in the ball park
Momentum = (mass) x (speed) (1 x 2) = (2 x 1). Their momenta are equal.
Height = 3*10 = 30 metres so GPE = m*g*h = 60*g*30 = 17,658 Newtons approx.
400000000 grams. This is because there are 1000 grams in one kilogram. ==== 1,000 g = 1 kg = 1,000 g / 1 kg To convert 400,000 kg to g, multiple 400,000 kg by the above conversion ratio as follows: 400,000 kg * (1,000 g / kg) = 400,000,000 g Note: kg cancel and you are left with grams as your unit of measure in your answer.
Momentum = M V = 10V = 10/M = 10/2= 5 meters per second
GPE = m*g*h = 294 Joules.

On earth: Potential energy = mgh so: 2kg * 9,81m/s^2 * 5m = 98,1 Joule
117600 = m (kg) * 9.8 m/s^2 * 200 mm = 60 kg.
The answer will depend on their positions (heights).
GPE = mgh = 4 x 9.8 x 3 = 117.6J
yes ====================== While your leg is swinging but before it hits the ball, your leg has kinetic energy. When your toe contacts the ball, it transfers kinetic energy to the ball, after which the ball also has some kinetic energy. (Your leg does not lose all of its kinetic energy, because it's still moving even after the ball takes off.)
GPE = mgh (mass x gravity x height). You can use 9.8 for gravity.
What is the question?
GPE=mgh hat : 15.68J trophy: 29.4J globe: 22.0J Therefore, the trophy has the greatest GPE.
A 0.650 kg basketball is dropped out of a window that is 6.46 m above the ground. The ball is caught by a person whose hands are 1.32 m above the ground. How much work is done on the ball by its weight?
529.2 J
