Multiple-Concept Example 7 deals with some of the concepts that are used to solve this problem. A cue ball (mass = 0.165 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick, which applies an impulse of +1.47 N.s to the ball. The ball then slides along the table and makes an elastic head-on collision with a second ball of equal mass that is initially at rest. Find the velocity of the second ball just after it is struck. Number i Units

A hockey player strikes a puck that is initially at rest. The force exerted by the stick on the puck is 967 N, and the stick is in contact with the puck for 4.2 ms (0.0042 s).  how do you find the impulse imparted by the stick to the puck. kg · m/sand , What is the speed of the puck  just after it leaves the hockey stick? mass of puck is 1.65kg m/s

A soccer ball with a mass of 0.427 kg approaches a player horizontally with a speed of 14.0 m/s. The player kicks the ball with her foot, which causes the ball to move in the opposite direction with a speed of 22.3 m/s. (a) What magnitude of impulse (in kg · m/s) is delivered to the ball by the player?  kg · m/s   (b)What is the direction of the impulse delivered to the ball by the player? - In the same direction as the ball's initial velocity  - Opposite to the ball's initial velocity       - Perpendicular to the ball's initial velocity  - The magnitude is zero.   (c) If the player's foot is in contact with the ball for 0.0600 s, what is the magnitude of the average force (in N) exerted on the player's foot by the ball?

A rubber ball of mass 29.5 g is dropped from a height of 1.95 m onto a floor. The velocity of the ball is reversed by the collision with the floor, and the ball rebounds to a height of 1.55 m. What impulse was applied to the ball during the collision?

A steel ball of mass 0.710 kg is fastened to a cord that is 89.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 2.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number i Unit (b) Number i Unit

A 130.0 g ball is moving horizontally to the west at 20.0 m/s when it is hit by a stick. The ball flies off to the 20.0° north of east at 45.0 m/s. What are the magnitude and direction of the impulse that the stick delivers to the ball? 4.90 Ns, 55.4° north of east 10.1 Ns, 76.1° north of east O 3.52 Ns, 34.6° north of east O 3.52 Ns, 55.4° north of east 8.34 Ns, 13.9° north of east O 4.90 Ns, 34.6° north of east 10.1 Ns, 13.9° north of east 8.34 Ns, 76.1° north of east

A cue ball at rest on a frictionless pool table is hit dead center by a pool stick, giving it an impulse of +1.85 N · s. The ball slides (the combination of hitting the ball dead center and no friction allows this to happen) along the table and makes a head-on elastic collision with another pool ball. If both pool balls have a mass of 0.156 kg, determine the velocity (in m/s) of the second ball the instant after the collision.

Two gliders with mA = 0.50 kg, mB = 0.40 kg, collide elastically on a frictionless surface. Glider A with a spring bumper initially moves to the right with the speed of 4.0 m/s and glider B with a spring bumper initially moves to the left with the speed of 7.0 m/s. What is the final velocity of the glider A after collision?

A 0.299-kg volleyball approaches a player horizontally with a speed of 12.6 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.0 m/s          (a) What impulse is delivered to the ball by the player? _____ kg-m/s (b) If the player's fist is in contact with the ball for 0.060 0 s, find the magnitude of the average force exerted on the player's fist. _____ N

37. Multiple-Concept Example 7 deals with some of the concepts that are used to solve this problem. A cue ball (mass = 0.165 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick, which applies an impulse of +1.50 N · s to the ball. The ball then slides along the table and makes an elastic head-on collision with a second ball of equal mass that is initially at rest. Find the velocity of the second ball just after it is struck.
