You and your friends are doing physics experiments on a frozen pond that serves as a frictionless, horizontal surface. Sam, with mass 80.0 kg, is given apush and slides eastward. Abigail, with mass 50.0 kg, is sent sliding northward. They collide, and after the collision Sam is moving at 37.0° north of eastwith a speed of 6.00 m/s and Abigail is moving at 23.0° south of east with a speed of 9.00 m/s. By how much did the total kinetic energy (in joules) of thetwo people decrease during the collision?

First, let's break down the problem step by step:1. We know the initial kinetic energies of Sam and…

Block A, with a mass of 0.410 kg, is traveling north on a frictionless surface with a speed of 5.00 m/s. Block B, with a mass of 0.480 kg, travels west on the same surface until it collides with A. After the collision, the blocks move off together with a velocity of 3.13 m/s at an angle of 42.5° to the north of west. What was B’s speed just before the collision?
The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.0430 kg and is moving along the x axis with a velocity of +6.70 m/s. It makes a collision with puck B, which has a mass of 0.0860 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a) puck A and (b) puck B.
Two asteroids of equal mass collide in an ellastic collision. Asteroid A has an initial velocity of 40 m/s. After the collision, asteroid A deflects an an angle of 30° above its initial direction. Asteroid B is initially at rest. After the collision, asteroid B travels at 45° below the original direction of asteroid A. What are the final speeds of the two asteroids?
Jack (mass 52.0 kg) is sliding due east with speed 8.00 m/s on the surface of a frozen pond. He collides with Jill (mass 48.0 kg), who is initially at rest. After the collision, Jack is traveling at 5.00 m/s in a direction 34.0° north of east. Ignore friction.
An astronaut comes loose while outside the spacecraft and finds himself floating away from the spacecraft with only a big bag of tools. In desperation, the astronaut throws his bag of tools in the direction of his motion (away from the space station). The astronaut has a mass of 102 kg and the bag of tools has a mass of 10.0 kg. If the astronaut is moving away from the space station at 1.80 m/s initially, what is the minimum final speed of the bag of tools (with respect to the space station) that will keep the astronaut from drifting away forever? minimum final speed: m/s
Two cars are approaching a perpendicular intersection without a stop sign. Car 1 has a mass m₁ = 800 kg and is heading north at V₁ 15 m/s. Car 2 has mass m2 = 700 kg and is heading west at an unknown speed v2. The two cars collide at the intersection, and stick together as a result of the collision.
