A proton (mass \(1.67 \times 10^{-27}\) kg, charge \(+e\)) is fired directly at a lithium nucleus (mass \(1.16 \times 10^{-26}\) kg, charge \(+3e\)). If the proton’s velocity is \(4.79 \times 10^5\) m/s when it is far from the nucleus, how far apart will the two particles be when the proton is at rest, just before it turns around? Assume the nucleus is free to recoil.[ ] m

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 1.8 ✕ 10−27 kg,moves in the positive y-direction with speed v1 = 5.4 ✕ 106 m/s. Another particle, of mass m2 = 9.0 ✕ 10−27 kg, moves in the positive x-direction with speed v2 = 3.2 ✕ 106 m/s. Find the magnitude and direction of the velocity of the third particle. Answer the following:
Two masses undergo a collision and they stick together. M1 has a mass of 550g and was traveling at an unknown velocity toward the second mass, M2=400g, which was traveling in the same direction at 4.5m/s. After the collision, they have a velocity of 5.1 m/s. Determine the velocity of the first mass before the collision.
In a very busy off-campus eatery, one chef sends a 201 g broccoli-tomato-pickle-onion-mushroom pizza sliding down the counter from left to right at 1.79 m/s. Almost simultaneously, the other chef launches a 335 g veggie burger (with everything, but hold the horseradish) along the same counter from right to left at 2.47 m/s. The two delicacies collide head-on at the given speeds. The counter is practically friction-free due to accumulated grease. The two delicacies merge into a single, unbelievably savory serving. In what direction does the merged meal move, if it moves at all? A) does not move B) to the right C) to the left At what speed does it move in m/s? Enter a positive number.

The Moon's craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 5.06 ✕ 1012 kg (about a kilometer across) strikes the Moon at a speed of 14.8 km/s. A. How much kinetic energy (in J) is lost in the collision? Such an event may have been observed by medieval English monks who reported observing a red glow and subsequent haze about the Moon. B. In October 2009, NASA crashed a rocket into the Moon, and analyzed the plume produced by the impact. (Significant amounts of water were detected.) Answer part (a) and (b) for this real-life experiment. The mass of the rocket was 2000 kg and its speed upon impact was 9000 km/h. speed of recoin (in m/s) loss of kinetic energy (in J)

15 75 Vb+w だ h A block of mass m,-1.28 kg slides to the right at a speed of 2.46 m/s on a frictionless horizontal surface, as shown in the figure. It "collides" with a wedge of mass mw, which moves to the left at a speed of 1.13 m/s. The wedge is shaped so that the block slides seamlessly up the Teflon (frictionless!) surface, as the two come together. Relative to the horizontal surface, block and wedge are moving with a common velocity Vb+w at the instant the block stops sliding up the wedge. a) If the block's center of mass rises by a distance h = 0.38 m, what is the mass of the wedge? The gravitational acceleration is g = 9.8 m/s². Express your answer in kg.
