Two football players with mass 75 kg and 100 kg run directly toward each other with speeds of 6 m/s and -8 m/s respectively. If they grab each other as they collide, the combined speed of the two players just after the collision?

During a game of football, a 108 kg player running at a speed of 9.1 m/s is tackled from the front by a 91 kg opponent at a speed of 6.3 m/s. What is the speed of the pair of players immediately after the collision (assuming the players are glued together)?

Shown is a collision between two pucks on an air hockey table. Puck a has mass 0.025kg and is moving along the x-axis with a velocity of +5.5m/s. It makes a collision with puck B, which has a mass of 0.05kg and is initially at rest. The collision is not head-on. After the collision the pucks fly off with the angles as shown. +5.5 m/s At rest Before collision 65 37- After collision What is the speed of puck A? (4) m/s What is the speed of puck B? (4) m/s

Two bodies of masses 8.5 kg and 4.9 kg move along the x-axis in opposite directions with velocities of 10.2 m/s (positive x-direction) and -8.0 m/s (negative x-direction), respectively. The two bodies collide and stick together. Find their combined velocities just after collision, expressing your answer in m/s.

two blocks (m1 and m2) are each released from rest at a height of h = 3.98 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.25 kg, determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure.

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   II.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.15 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   III.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.24 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic…

What is the velocity of a 900-kg car initially moving at 30.0 m/s, just after it hits a 150-kg deer initially running at 12.0 m/s in the same direction? Assume the deer remains on the car. What type of collision is in this problem? elastic, inelastic, plastic, deadly

A 65.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped at him at a velocity of 28.0 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities (in m/s) be in this case? (Assume the original direction of the ice puck toward the goalie is in the positive direction. Indicate the direction with the sign of your answer.) puck m/s goalie m/s

A 50 kg50 kg soccer player jumps vertically upwards and heads the 0.45 kg ball as it is descending vertically with a speed of 30 m/s. (a) If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic? (b) If the ball is in contact with the player's head for 21 m/s, what is the average acceleration of the ball? (Note that the force of gravity may be ignored during the brief collision time.)

An archer fires a 120 g arrow at a velocity of +31.5 m/s toward an apple sitting on a stump. The arrow sticks into the apple and knocks it off the stump at a speed of +16.8 m/s. In kilograms, calculate the mass of the apple. Is this collision elastic or inelastic?
