A 0.14 kg bead slides on a straight frictionless wire and moves with a velocity of 9.5 m/s to the right. The bead collides with a larger 0.12 kg bead that is initially at rest. After the collision, the smaller bead moves with a velocity of 0.73076923076923 m/s. (use many decimal points in your answer in order to make sure you get it exact) a.What is the large bead's velocity after the collision? b.What is the total kinetic energy of the system of beads after the collision? c.What was the total kinetic energy of the system of beads before the collision?

A moving cart of mass 3.5 kg crashes into a stationary cart of mass 10.5 kg as shown. The carts are prevented from touching one another during the collision by a pair of neodymium magnets mounted on the ends of the carts and positioned for repulsion. After separating, the more massive cart moves to the right at 1.4 m/s. What are the final speed and direction of motion of the less massive cart? strong magnets Vfi VGi = 0 3.5 kg 10.5 kg Frictionless surface

In a football game, a receiver is standing still, having just caught a pass. Before he can move, a tackler, running at a velocity of +3.77 m/s, grabs him. The tackler holds onto the receiver, and the two move off together with a velocity of +1.82 m/s. The mass of the tackler is 94.1 kg. Assuming that momentum is conserved, find the mass of the receiver. Number i Units Before collision After collision

Answer the question correctly. Thank you!

A Z Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.8 m/s. Olaf's mass is 69.7 kg.( Figure 1) 2 masteringphysics.com/mycitemView?assignment ProblemID=189028758&offset=next W S Figure X command A # 3 20 E D C $ B 4 888 R F I % 5 of V 254 FD T G 6 B Part A 20 If Olaf catches the ball, with what speed ty do Olaf and the ball move afterward?

A 2,300-kg car moving east at 10.0 m/s collides with a 3,000-kg car moving north. The cars stick together and move as a unit after the collision, at an angle of 33.0° north of east and at a speed of 5.17 m/s. Find the speed of the 3,000-kg car before the collision.

A 2.80 kg object initially moving in the positive x-direction with a velocity of +4.69 m/s collides with and sticks to a 2.01 kg object initially moving in the negative y-direction with a velocity of -2.74 m/s. Find the final components of velocity of the composite object. (Indicate the direction with the sign of your answer.)

Can you help me with this problem A 0.156 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/sm/s. It has a head-on collision with a 0.291 kg glider that is moving to the left with a speed of 2.15 m/s Suppose the collision is elastic.Find the magnitude of the final velocity of the 0.156 kg glider in m/s.
