- Ball A, whose mass is 12.0 kg, is moving with a velocity of 37.0 m when it suddenly hits another ball at rest, Ball B. After the collision, Ball A continues to move with a velocity of 19.0 m/s while Ball B moves with a velocity of 4.00 m/s. What is the mass of Ball B?A 3.00 kg and 2.00 kg object have initial velocities of 3.00 m/s i and -2.00 m/s i respectively. After colliding, the final velocity of the 3.00 kg mass is 0.750 m/s i. What amount of kinetic was lost in the collision?Two 2712 kg train cars roll toward each other (Car A at 0.34 m/s, Car B at -2.5 m/s) on a level track. After they collide and couple together, what is the final velocity of the two-car object?
- 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.) m/sA 1200-kg car moving at 15.6 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? 5.5 m/s O 8.6 m/s O 6.9 m/s O 12.1 m/sA 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 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?In the figure below, the green ball has a mass of 2.6 kg and is traveling to the right with an initial velocity of 4 m/s. The yellow ball has a mass of 1.04 kg and is traveling the left with an initial velocity of -6 m/s. After the two balls collide, the green ball travels to the left with a speed of -2.9 m/s, what must be the velocity of the yellow ball after the collision? In order to answer this question, follow the steps provided and remember that the total initial momentum of the system must equal the total final momentum. A summary of what we know about each ball is given belowGreen Ball: Mass = 2.6 kg, Initial Velocity = 4 m/s, Final Velocity = -2.9 m/sYellow Ball: Mass = 1.04 kg, Initial Velocity = -6 m/s, Final Velocity = UNKNOWN Momentum Before the Collision (a) What was the initial momentum of the green ball before the collision?pTi = 10.4 kg m/s (b) What was the initial momentum of the yellow ball before the collsion?pTi = -6.24 kg m/s (c) What was the total initial…Puck 1 (0.5 kg) travels with velocity 80 m/s to the right when it collides with puck 2 (1 kg) which is initially at rest. After the collision, puck 1 moves with a velocity of 0 m/s. Assume that no external forces are present and therefore the momentum for the system of pucks is conserved. What is the final velocity (in m/s) of puck 2 after the collision?
- An 80 kg running back moving at 5.0 m/s attempts to dive directly across the goal line for a touchdown. Just as he reaches the line, he is met head-on in mid-air by two 75 kg linebackers both moving in the direction opposite the running back at 2.8 m/s. They all become entangled as one mass.
