A father gently places his son on a rotating merry-go-round. The merry-go-round is essentially a disk with a mass of 250 kg and a radius of 2.5 m initially rotating at one revolution every 5.00 seconds...

Fig: a earth of radius R and particle is at height H=R and projected from there is the particle shown in the figure is projected with orbital velocity V=√(GM/2R) it returns after time...

An object is on a flat surface. Why is it not 6D? Any help would be appreciated! full question: An object is on a flat surface. If a spring is compressed x= -D by the object, then...

The block is released and slides a total distance of 1.5 m along a rough horizontal surface before stopping. Assume that the surface has a kinetic coefficient of friction μk = 0.3. What is the...

Assuming that the surface has a coefficient of kinetic friction of 0.3, how far up the plane will the block go before stopping? I got a = -g*[sinΘ + µ*cosΘ] = -8.551 m/s² d = v²/(2a)...

A 0.300 kg air-track glider moving at 2.20 m/s bumps into a 0.800 kg glider at rest. a.) Find the total kinetic energy after collision if the collision is elastic. b.) Find the total...

Explain how potential energy, kinetic energy, and total mechanical energy change form in a swinging pendulum, and how the speed changes as a pendulum swings back and forth without friction. Include...

Describe at least three of the transformations from one form of energy to another that occur in changing nuclear energy at a power plant to the energy delivered to your home via an electrical wall...

A mole of gold atoms are arranged in a cube. A 1 kg mass is placed on top of the cube. The interatomic spacing for gold is 10^−10 m andYoung’s modulus of gold is 1011 N/m2. Given there...

What are the advantages of using pulleys? What do you think would happen to the mechanical advantage if you added a third movable pulley?

The coefficient of friction between a race car’s wheels and the track is 1. The car starts from rest and accelerates at a constant rate for 200 m. Find the velocity at the end of the race.

There's a project where I'm supposed to do this, I need to know this for my project, thank you!

a ball is thrown straight up from the edge of a building and takes 1.3 seconds to reach its highest point. it continues on its flight and falls to the ground, taking an additional 3.3 seconds ( for...

Your friend likes listening to music on vinyl records rotating at 33.3 revolutions per minute. If he listens to music about 3 hours per day, estimate the number of revolutions his turntable makes...

Briefly summarize how the pulleys worked with respect to changes in effort force and effort distance compared with resistance force and resistance distance. What are the advantages of using pulleys...

A sailor pushes a 195.0 kg crate up a ramp that is 2.00 m high and 6.00 m long onto the deck of a ship. He exerts a 750.0 N force parallel to the ramp. What is the mechanical advantage of the ramp...
