A 750-g disk sliding along frictionless ice with a speed of 8.5 m/s strikes a stationary rod-disk combo 12-cm from its center-of-mass. This rod-disk combo is made from a 360-g rod that is 35-cm long, with 2 150-g solid disks of radius 7.0-cm attached, one on each end of the rod. After the perfectly elastic collision, the disk moves off along a path that is 28º above its original path, while the rod-disk combo spins about its center-of-mass as it moves off at an angle as well. Using this information, find the translational speed of both objects after the collision, the angular speed of the rod-disk combo, and the angle of its trajectory.

A 2.90-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring. (a) Determine the force constant of the spring, if the box compresses the spring 5.30 cm before coming to rest. (b) Determine the initial speed the box would need in order to compress the spring by 1.50 cm.

A 10 kg mass is sliding at 8 m/s along a frictionless floor toward an ideal...

A 10 kg mass is sliding at 8 m/s along a frictionless floor toward an ideal massless spring. When the mass hits the spring, they stick together without any loss of energy. The mass stops briefly at x = +4.2 m before moving back toward equilibrium. (Assume x = 0 at the point at which the mass sticks to the spring and t = 0 when the mass first makes contact with the spring.)a)What is the spring constant of the...

A(n) 8.5-kg object is sliding across the ice at 2.34 m/s in the positive x direction. An internal explosion occurs, splitting the object into two equal chunks and adding 11 J of kinetic energy to system. The explosive separation takes place over a 0.16-s time interval. Assume that the one of the chunks after explosion moves in the positive x direction. The x component of the average acceleration of this chunk during the explosion is afrontx, the x component fo...

A block weighing 259 g slides along a frictionless track at a speed 6.1 cm/s. It then attaches to a spring-bumper with an electromagnetic device so that the block attaches to the bumper. The bumper has a mass of 130 g, and the spring has a stiffness of 1540 kg/s2 and an equilibrium length of 10.6 cm. After the spring compresses and returns to its original length, the magnet turns off and the block launches off again, conserving energy. (a)...

A 10 g marble slides to the left at a speed of 0.4 m/s along a frictionless surface. It has a head-on, elastic collision with a larger, 30 g marble sliding to the right at 0.2 m/s. Since the collision is head-on, all motion is along the x-axis. a. Find the total kinetic energy AND the total momentum before the collision b. The marbles bounce off each other elastically. Each marble has a different velocity after the collision. The lighter...

A 8-g bullet moving horizontally with speed of 250 m/s strikes and remains in a 4.0-kg block initially at rest on the edge of a table. The block, which is initially 80 cm above the floor, strikes the floor a horizontal distance from the base of table. What is the horizontal distance on the floor?

A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision,...

A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and move at some final speed. Which of the following describes the change in momentum and energy of the puck during the collision? The puck loses some, but not all, of its original momentum and mechanical energy. One cannot determine if the momentum or energy of the puck is conserved without knowing the final velocities and masses two objects. The puck conserves...
