Two blocks, of masses M = 2.0 kg and 2M, are connected to a spring of spring constant k = 200o N/m that has one end fixed as shown in Figure 2. The horizontal surface and the pulley are frictionless, and the pulley has negligible mass. The blocks are released from rest with the spring relaxed. What maximum distance does the hanging block fall before momentarily stopping? 3.90 m

ANSWER IS 390. PLEASE SHOW WORK!!!

Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use!If your building is on fire, simply reach out and grab the cord on the OyOy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 94.0 kg and is shaped like a cylinder of radius R = 0.810 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0800 meters. The cord is wound around the small shaft and this is the secret to your low velocity. We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 85.5 kg is using the OyOy and begins his decent from an initial height of y0 = 11.20 meters.Determine all the following:The…

I am having trouble with this homework problem, any help would be greatly appreciated, thank you!

A 23 kg child goes down a straight slide inclined 38 degrees above horizontal. The child is acted on by his weight, the normal force from the slide, kinetic friction, and a horizontal rope exerting a 30 N force as shown in the figure(child is being pulled from rope going left to right ontop of slide). How large is the normal force of the slide on the child?

Question 12 of 12 Ø Attempt 1 A constant applied force F, of 13.0 N pushes a box with a mass m = 7.00 kg a distance x = 15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is 0.130. Fp m Assuming that the box starts from rest, what is the final velocity vf of the box at the 15.0 m point? Uf = 4.5 m/s %3D Incorrect If there were no friction between the box and the floor, what applied force Fnew Would give the box the same final velocity? about us careers privacy policy terms of use contact us |help MacBook

The coefficient of static friction between mass mA and the table is 0.48, whereas the coefficient of kinetic friction is 0.27. Ignore masses of the cord and the (frictionless) pulley. What minimum value of mA will keep the system from starting to move? What value of mA will keep the system moving at constant speed?

Starting from rest, a 93-kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a magnitude of 840 N, and his speed at the bottom of the pole is 3.6 m/s. How far did he slide down the pole? ho

The diagram shows all the forces on an object with mass m = magnitude of the acceleration of the object? 89 kg. What is the 480 N Select one: O 9.4 m/s? 30° O 6.0 m/s? 3.0 m/s? 120 N O 4.5 m/s sine and cosine reversed. Check that you didn't get 11.5 m/s? 240 N

A 0.1 kg ball is launched from a vertical cannon, 0.7 m high and 0.05 m wide. The cannon exerts a 146 N force on the ball for a period of 0.03 s. What is the final height ofthe ball?
