If you have an object with a mass of 385 grams, and it is moving at a speed of 2.637 m/s, what is its' kinetic energy in Joules? Your Answer:

What is the speed of a 2.5-kilogram mass after it has fallen freely from rest through a distance of 12 meters?

The New Horizons spacecraft (mass 478 kg) was launched from earth in 2006 and flew past Pluto in 2015. What minimum amount of work has to be done on a spacecraft of this mass to send it from the earth’s surface to infinitely far away from the earth? Neglect air resistance and the gravitational effects of the sun, moon, and other planets.

A nuclear power reactor generates 3.00 x 10^9 W of power. In one year, what is the change in the mass of the nuclear fuel due to the energy conversion? (A 1 W power source gives 1 J/s)

How much energy is required to move a 1000-kg object from the Earth's surface to an altitude twice the Earth's radius?

What is the kinetic energy of a mass of 4 KG moving with velocity 8 m/sec

If you are going to launch a 10,000 kg spacecraft from Earth, (a) how much kinetic energy it must possess in order to escape the gravitational pull? (b) If the mass is reduced by 5,000 kg, how much kinetic energy is required?

How to find Kinetic Energy?  KE= 1/2mv1 2   m= 60 grams      v1= 688.75

Lindsay is in an airplane, preparing to skydive. Lindsay has a mass of 71.1 kg, and the airplane is flying at an altitude of 3620 m above the ground. Before she jumps from the airplane, how much gravitational potential energy does he have?   6.44∗10^5 J   1.90∗10^6 J   2.52∗10^6 J   2.57∗10^5 J

Momentum and Impulse: 1. p= mü 2. Ï = Fat Energy: 3. ¡=mAv 4. i = Ap 1. W = F.d 2. KE= 3. GPE = mgh P = momentum; Ap=Pj-Po m = mass Δύ= B - Bo V = velocity; 1 = impulse F = force t = time; W = work d At = tr-to d=displacement KE Kinetic Energy GPE Gravitational Potential Energy h = height Gravity g = -9.81 m/s² A rocket is launched from rest at ground level. The air resistance, or drag force, of the rocket is known to be F = -0.75 N. The engine of the rocket has enough fuel to last t = 0.80 s, providing a total impulse of 7₂ = 2.20 N-s, which is called the thrust stage. After the engine runs out of fuel, the rocket coasts to its maximum height before falling back to the ground, which is called the coast stage. Draw force diagrams of the rocket during the two stages of the problem: Thrust Stage Coast Stage
