University Physics 1 - Conservation of Momentum I need help with this problem and an explanation of the solutions described below:   Pick one of the collisions (identify which one it is) from the air track collision experiment. Collision 2 ( described in the image below)  and calculate the mechanical energy both before and after the collision. Was energy lost or gained? If it was lost, where did it go? If it was gained, where did it come from?

Nate the Skate was an avid physics student whose main non-physics interest in life was high-speed skateboarding. In particular, Nate would often don a protective suit of Bounce-Tex, which he invented, and after working up a high speed on his skateboard, would collide with some object. In this way, he got a gut feel for the physical properties of collisions and succeeded in combining his two passions.* On one occasion, the Skate, with a mass of 115 kg, including his armor, hurled himself against a 891 kg stationary statue of Isaac Newton in a perfectly elastic linear collision. As a result, Isaac started moving at 1.45 m/s and Nate bounced backward. What were Nate's speeds immediately before and after the collision? (Enter positive numbers). Ignore friction with the ground. speed before: m/s speed after: m/s *By the way, this brief bio of Nate the Skate is written in the past tense, because not long ago he forgot to put on his Bounce-Tex before colliding with the Washington Monument in…

B. Ball Game (Practice Activity – answer key below) 1. A neophyte player catches a 125 g ball moving at 25.0 m/s in 0.02 s. A professional player catches the same ball in 1.0 s by slightly retracting his hand during the catch. Find the forces exerted by the ball on the hands of the two players. 2. Two balls A and B are approaching each other with velocities 4.5 m/s, right and 7.2 m/s, left, respectively. The mass of ball A is 3.2 kg, while that of ball B is 5.6 kg. Find the velocity of the two bodies after impact, assuming that the collision is perfectly inelastic.

Course Contents Homework Ch06 Prob0656 problem Timer Notes Evaluate Feedback Print Infa Ignore air friction for the following problem. If you throw a stone upwards with a speed greater than the escape speed, it will continue to move away from Earth forever and never return. The escape speed on Earth is 11.186 km/s. Now consider that you throw a stone directly in the direction of the Moon (it is ok to ignore the rotational motion of the Moon around the Earth). What is the minimum speed that you need to give the stone so that it makes it to the Moon? It is recommended to carefully think about this problem and then use energy conservation to find a solution. Even for the minimum speed the stone will have a large velocity when it reaches the Moon. You can use the following data: mass of Earth is 5.972 x104 kg, mass of the Moon is 7.348 x1022 kg, distance Earth-to-Moon is 384.4 x10 m, radius of Earth is 6.371 x10 m. The solution requires at least 4 correct digits 11066 m/s Submit Answer…

Hi, please someone help me on this. I hope my question does not get sent back for the third time again. In this photo, I want you guys to estimate her mass in kg and her height in meters and follow the other two bullets, thank you

From YOUR personal experiences, draw a picture where the net force = 0 on a moving object. Each picture must include 1. Arrows and labels for the vector forces that cancel. 2. A short (one or two sentence) description of the motion that describes What the object was doing. The evidence indicating that the object’s momentum is conserved. Cite evidence of both constant speed and constant direction.
