A 92-kg fullback moving south with a speed of 5.8 m/s is tackled by a 110-kg lineman running west with a speed of 3.6 m/s. Assuming momentum conservation, determine the speed and direction of the two players immediately after the tackle.

A 5.75 kg bowling ball moving at 9.20 m/s collides with a 0.860 kg bowling pin, which is scattered at an angle of 85.0° to the initial direction of the bowling ball and with a speed of 14.0 m/s. (Assume the bowling ball is initially moving in the +x-direction.) (a) Calculate the final velocity of the bowling ball. (Find the magnitude in units of m/s and direction in degrees counterclockwise from the +x-axis). magnitude m/s direction ° counterclockwise from the +x-axis (b) Is the collision elastic? O Yes O No (c) Linear kinetic energy is greater after the collision. Discuss how spin on the ball might be converted to linear kinetic energy in the collision.

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1750 kg and was approaching at 7.00 m/s due south. The second car has a mass of 900 kg and was approaching at 19.0 m/s due west.   (a)Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look for other simplifying aspects.) magnitude _______________ m/s   direction ° _________________ counterclockwise from west   (b)How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.) ________________________ J

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1050 kg and was approaching at 4.00 m/s due south. The second car has a mass of 900 kg and was approaching at 22.0 m/s due west. (a) Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars.
