Your answer is partially correct. Try again. A 75.6-kg person, running horizontally with a velocity of +2.66 m/s, jumps onto a 18.6-kg sled that is initially at rest. (a) Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away. (b) The sled and person coast 30.0 m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow? Number 2.13 JUnits...

At the end of the race a person with a mass of 45.0 kg jumps out in front of the 240.0kg bobsled which is going 12.0 m/s horizontally. Initially the person is at rest. The person sticks to the front of the bobsled after the collision. What is the initial momentum of the sled, persons system? What is the momentum of the system after the collision?) What is the final velocity of the sled and person. What is the change...

Your answer is partially correct. Try again. A 6.98-9 bullet is moving horizontally with a velocity of +364 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks...

Chapter 10, Problem 45 GO Your answer is partially correct. Try again. The length of a simple pendulum is 0.85 m and the mass of the particle (the "bob") at the end of the cable is 0.34 kg. The pendulum is pulled away from its equilibrium position by an angle of 7.9° and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. (a) What is the angular frequency of the...

Chapter 07, Problem 36 GO Your answer is partially correct. Try again. Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision Momentum is conserved. Object A has a mass of mA = 16.6 kg and an initial velocity of VOA 7.80 m/s, due east. Object B, however, has a mass of mB = 28.2 kg and an initial velocity of V08-5.83 m/s, due north. Find the...
