Two people want to do a physics experiment at the bowling alley. They set up sensors to measure velocities and then roll two bowling balls with different masses so that they hit head on and collide elastically. The table summarizes the values known for the collision. Given the information, what is the mass of ball 2? Ball 1 Ball 2 mass (kg) 5.05.0 ?? initial velocity (m/s) 7.07.0 −3.0−3.0 final velocity (m/s) −7.74−7.74 2.262.26

A 1200-kg car moving at 19.4 m/s suddenly collides with a stationary car of mass 1500 kg. If the two vehicles lock together, what is their combined velocity immediately after the collision? 12.1 m/s 5.5 m/s 6.9 m/s O 8.6 m/s

m Q6. A 6.0 kg block is sliding to the east across a horizontal, frictionless surface with a momentum of 30 kg. It strikes an obstacle. The obstacle exerts an impulse of 10 N.s to the west on the block. Find the speed of the block after the collision. (3.3 m/s)

A 10.50-g bullet is fired into a stationary block of wood having mass m = 4.980 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.6090 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.) O 289.449

Two remote control cars with masses of 1.15 kilograms and 1.98 kilograms travel toward each other at speeds of 8.41 meters per second and 3.97 meters per second, respectively. The cars collide head-on, and the less massive car recoils with a speed of 2.25 meters per second.a. What is the final speed of the second car?  b. How much kinetic energy is lost in this collision?

A green pool ball (p = 30 kg x m/s) moves towards a yellow pool ball (p = -9 kg x m/s).  Then, the two pool balls collide.  After the collision, the green pool ball has a momentum of 3 kg x m/s.   How much momentum does the yellow pool ball have after the collision?  Explain your answer.

Two cars collide at an intersection. Car A�, with a mass of 1900 kgkg , is going from west to east, while car B�, of mass 1300 kgkg , is going from north to south at 14.0 m/sm/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 55.0 ∘∘ south of east from the point of impact.How fast were the enmeshed cars moving just after the collision?

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

Two clay balls collide and stick. Ball 1 has a mass of 3 kg and an initial velocity of 10 m/s in the positive x direction. Ball 2 has a mass of 10 kg and an initial velocity of 12 m/s in the negative x direction. What is the final velocity of the combined mass?

A volleyball is spiked so that its incoming velocity of + 2.50 m/s is changed to an outgoing velocity of - 20.7 m/s. The mass of the volleyball is 0.350 kg. What is the magnitude of the impulse that the player applies to the ball?
