- 3. Harry Potter is doing his usual thing of cruising around looking for the Golden Snitch when a rogue bludger drills him in the arm. We can assume that the bludger is initially moving at a speed of 15.0 m/s and hits Harry directly from the side. If Harry had been moving forward with a speed of 24.0 m/s and the bludger and Harry stick together after the collision, what is their final velocity (both magnitude and direction)? Assume that Harry has a mass of 48.0 kg (including his Nimbus 2000) and that the mass of a bludger is 25.0 kg. m B = 25.0 kg B = 15.0 m/s Bam! Harry+Bludger v = ?

While m2 = 10kg is initially at rest, horizontally moving mị = 6kg with a speed of v1 = 11.8m/s collides with it. After the collision, the two masses scatter with speeds of v, = 7.8m/s and v,. If 01 = 48°, determine the speed of m2 after the collision, v, =?. Express your answer in units of m/s with one decimal place.

- Two protons collide in a perfectly elastic collision. All motion occurs along a straight line. The first proton is moving at 6.90 x 106 m/s and the other is moving in the opposite direction at 11.0 x 106 m/s. What are their velocities after the collision?arrow_forwardThree identical train cars, coupled together, are rolling east at speed v0v0. A fourth car traveling east at 2v0v0 catches up with the three and couples to make a four-car train. A moment later, the train cars hit a fifth car that was at rest on the tracks, and it couples to make a five-car train.What is the speed of the five-car train?arrow_forwardThe figure below shows a titanium ball with a mass of 3.30 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v = 10.0 m/s), and the angle its path makes with the wall is ? = 60.0°as shown. (Because we are analyzing the motion of the ball over a very short time just before and after impact, you may safely ignore the effect of gravity on the ball.) The ball is in contact with the wall for 0.206 s. What is the average force (in N) exerted by the wall on the ball during the impactarrow_forward
- A uranium nucleus (mass 238 units) at rest decays into helium nucleus (mass 4.0 units) and thorium nucleus (mass 234 units).

A 4 × 10-4 slug revolver bullet is fired to the +x direction into a 0.002-slug hanging light bulb supported by a wire. The revolver bullet sticks inside the bulb.

In one such decay, the electron and the neutrino are emitted at right angles to each other. The electron (mass 9.11 x 10-31 kg) has a speed of 5.00 x 107 m/s and the neutrino has a momentum of 8.00 x 10-24 kg • m/s. What is the recoil speed of the nucleus?arrow_forward
