А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...

1. A 185 g cart is given a quick push up a frictionless incline, giving it an initial velocity of 1.45 m/s. The incline is at an angle of 10.0 to the horizontal. You must show your work to get full credit for this problem. a) What is the cart's initial kinetic energy, i.e. when it leaves the launcher? KE =mv eay @ztty =C85k9)(145s) = .1343 b) What is the cart's change in kinetic energy (Kr-Ko) from the launch point...
Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with mass m1 = 16.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is a = 1.40 m/s2, and the tension in the segment of string attached to this block is T1. The hanging block has a mass of m2 = 23.5 kg, and the tension in the string attached to it is T2....
A 5 kg block supported by a string rests on a frictionless incline. The length of the string is 0.1 m and its mass of 4.9 g ≪ 5 kg. – 0.1 m - mi 5 kg 0 = 1 53° Find the time it takes a transverse wave to travel from one end of the string to the other. The acceleration of gravity is 9.8 m/s?. Answer in units of ms.
You pull on a string with a horizontal force F = 34 N that is attached to a block of mass mb = 7.1 kg, then to the axle of a solid cylinder of mass mc = 5.7 kg and radius r = 0.4 m, then to a spring of spring constant k = 115 N/m. This is all done on an inclined plane where there is friction ( Us = 0.6 and k = 0.30 ), and the incline...
8. A 30.0-kg block slides down a frictionless incline. If the block starts from rest and has a speed of 3.00-m/s at the bottom, at what vertical distance did the block start its descent Answer: 0.459 m 9. It is found that a force of 18-N is required to stretch a spring by 0.300 meters from its natural length. (a) What is the spring constant of the spring? (b) How much energy is stored in the spring when it is...
