- A young 45 kg45 kg ice hockey goalie, originally at rest, deflects a 0.14 kg0.14 kg hockey puck slapped at him at a speed of 34.5 m/s34.5 m/s. In this problem, take the original direction of the puck as positive. Suppose the goalie and the hockey puck have an elastic collision and the puck is reflected back in the direction from which it came. What would the final velocity, in meters per second, of the goalie be in this case?A 4.0-kg mass, initially at rest on a horizontal frictionless surface, is struck by a 2.0-kg mass moving along the x axis with a speed of 8.0 m/s. After the collision, the 2.0-kg mass has a speed of 4.0 m/s at an angle of 37° from the positive x axis. What is the speed of the 4.0-kg mass after the collision?0.453 kg ball is thrown at a stack of 15.8 cm tall, mo = 0.383 kg objects and hits with a As part of a carnival game, a mb = perfectly horizontal velocity of Voi = 11.8 m/s. Suppose that the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of vb.f = 4.35 m/s in the same direction, the topmost object has an angular velocity of w, = 5.23 rad/s about its center of mass, and all the remaining objects are undisturbed. Assume that the ball is not rotating and that the effect of the torque due to gravity during the collision is negligible. If the object's center of mass is located r = 11.1 cm below the point where the ball hits, what is the moment of inertia I, of the object about its center of mass? Vbi I, = kg - m? What is the center of mass velocity vo.cm of the tall object immediately after it is struck? m/s Vo,cm Vp.f
