Three ice skaters meet at the center of a rink and each stands at rest facing thecenter, within arm’s reach of the other two. On a signal, each skater pushes themselves away fromthe other two across the frictionless ice. After the push, Skater A with mass 80 kg moves in thenegative y-direction at 3.5 m/s and skater B with mass 75 kg moves in the negative x-direction at4 m/s. Find the x- and y-components of the 90 kg Skater C’s velocity after the push. Assume abirds-eye view of the situation for your coordinates.
A 40-kg football player leaps through the air to collide with and tackle a 60-kg player heading toward him, also in the air. Ifthe 40-kg player is heading to the right at 7 m/s and the 60-kg player is heading toward the left at 3 m/s, what is theresulting speed of the tangled players?
To balance a 35.5-kg automobile tire and wheel, a mechanicmust place a 50.2-g lead weight 25.0 cm from the center of thewheel. When the wheel is balanced, its center of mass is exactly atthe center of the wheel. How far from the center of the wheel wasits center of mass before the lead weight was added?
A nucleus that captures a stray neutron must bring the neutronto a stop within the diameter of the nucleus by means of thestrong force. That force, which “glues” the nucleus together, is approximatelyzero outside the nucleus. Suppose that a stray neutronwith an initial speed of 1.4 * 107 m/s is just barely captured by anucleus with diameter d = 1.0 * 10-14 m. Assuming the strongforce on the neutron is constant, find the magnitude of that force.The neutron’s mass is 1.67 * 10-27 kg.
A football player with a mass of 60 kg and a velocity of 10 m/sec due east collides head-on with a defensive back with a mass of 90 kg and a velocity of 4 m/sec in the opposite direction (due west). If they stick together after the collision and external forces can be ignored, what is their joint speed after the collision?
Suppose a fireworks shell explodes, breaking into three large pieces for which air resistance is negligible. How does the explosion affect the motion of the center of mass? How would it be affected if the pieces experienced significantly more air resistance than the intact shell?
