What is the gravitational potential energy of a 1000 kg car on top of a 45 m cliff? Please show all steps
The gravitational potential energy gained by a box having a mass of 2 kg that is lfted to a height of 4 m is 8 joules. asking if it is true or false
4. A mass of 2 kg is held 4 meters above the ground. The gravitational potential energy of this object, relative to the ground, is ___. 5. Which is easier, stopping a 1000 kg car traveling at 40 m / s or a 2000 kg car traveling at 20 m / s? 8. Suppose an airplane fires bullets in the same direction it travels. Does the momentum of the plane increase, decrease or remain the same? Explain
An object, m = 2 kg, is dropped from the top of a building whose height is h=20 m above the ground. Assume that g=9.8m/s2 What is its gravitational potential energy with respect to the ground?
Part (b)
Using m is 4.00 kg and r is 60.0 cm, calculate the gravitational
potential energy in case 1 above.
Note that a number such as 1.23 x 10^-9 can be entered as
1.23e-9

Determine values for translational kinetic energy, gravitational potential energy, elastic potential energy, and total energy at 0 m, 0.2 m, and 0.4 m above the release point for a 2 kg object pulled 0.2 m downward from the equilibrium position and released from rest while attached to the end of a vertical spring with k = 50 N/m. Be aware that the spring is stretched at the release position and at the equilibrium position so you will have to use...
Do not assume a constant g for this problem. The gravitational potential energy of a 1 kg object on the earth's surface is -6.28e7 J. How much work is required to lift that object to a height of 5e6 m? GM = 4e14m^3/s^2. Radius of earth = 6.4e6 m.
2 kg mass compresses a spring 1.2 m. If the object has 160 J of energy, calculate the spring constant of the spring.
Part A Select the equation that shows that the gravitational potential energy of a 1300-kg boulder raised 4 m above ground level is 52000 J. (You can express g in units of N/kg, because m/s? is equivalent to N/kg) mgh = (1300 kg)(10N/kg) (4 m)-52000 J 2 2 421) N2000J 0 PE-yMgh-V(1300kg)(10N/kg)(4m) o PE-mg-(1300 kg)(10 N/kg) (4 m) 52000 J PE = mgh = (1300 kg)(10 N/kg)(4 m) = 52000 J Submit Provide Feedback Next >
