A projectile (m, = 75 g) traveling at v = 535 m/s strikes and becomes embedded in the block (m, = 40 kg), which is initially stationary. Compute the energy lost during the impact. Express your answer as an absolute value |AE| and as a percentage n of the original system energy E. Answers: JAE| = n = i

A 150-g particle on the inside of a smooth hemispherical bowl of radius R 35.0 cm (see the figure below) is released from point A at rest. Its speed at B is 1,10 m/s. (a) What is its kinetic esergy at B? T h (b) How much mechanical energy is lost as a result of friction as the particle goes from A to B2 (c) Is it possible to determine u from these results in a simple manner? O Yes O No Explain. ..

This time, the pendulum is 1.51 m long and has a mass of 3.01 kg. You give it a push away from vertical so that it starts swinging with a speed of 2.25 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down? 1 44.2 degrees 2 39.1 degrees 3 31.6 degrees 4 34.0 degrees

A 71.1-kg boy is surfing and catches a wave which gives him an initial speed of 1.60 m/s. He then drops through a height of 1.59 m, and ends with a speed of 8.51 m/s. How much nonconservative work (in kJ) was done on the boy?

A box with mass 1.78 kg is being pulled across a rough surface with a coefficient of kinetic friction Hk = 0.398. The pulling force has a magnitude %D of 14.5 N and is directed at an angle 20.4 degrees above horizontal. If the box is dragged a distance of 10.8 m, what is the total energy lost to friction? (Hint: be sure to account for the upward component of the pulling force.) Image size: s ML Max F 9. m Dlogno ont mote oro

Same set-up for the conservation of energy was performed. The 5-g marble covered a horizontal distance of 40 cm from the edge of the ramp (horizontal) from an elevation of 15 cm above the ground. At what height (in cm) relative to edge of the ramp was the marble released? Use g=9.8 m/s2. Round off your answer to two decimal places.

This time, the pendulum is 1.55 m long and has a mass of 3.05 kg. You give it a push away from vertical so that it starts swinging with a speed of 1.27 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down?     14.4 degrees     18.7 degrees     17.3 degrees     18.0 degrees

An 7.6 kgkg crate is pulled 5.4 mm up a 30∘∘ incline by a rope angled 19 ∘ above the incline. The tension in the rope is 140 NN and the crate's coefficient of kinetic friction on the incline is 0.23.How much work is done by tension, by gravity, and by the normal force?What is the increase in thermal energy of the crate and incline?

Problem 10.12 2 The maximum energy a bone can absorb without breaking is surprisingly small. Experimental data show that a leg bone of a healthy, 60 kg human can absorb about 240 J. W S X H mmand / # 3 E E D C 4 888 R F - 1 % 5 V 7 T G ▾ Part A 1 6 B From what maximum height could a 60 kg person jump and land rigidly upright on both feet without breaking their legs? Assume that all energy is absorbed by the leg bones in a rigid landing.
