- A 5kg rifle is attached to a horizontal cable such that it will freely move neglecting friction. If the rifle is made to fire a 50g bullet with a muzzle velocity of 300m/s, what will be the velocity of the rifle as it moves opposite the direction of the bullet? 1.What is the correct formula to use to this sample problem? 2.What type of collision happen from the given situation of the sample problem? 3.Defend/Prove your answer for item number 2 4.Show your complete solution in calculating the Velocity of the Gun?One 20.0 kg cart starts, initially at rest, reaches a velocity of 10.0 m/s while another cart of mass 15.0 kg reaches a velocity of 20.0 m/s while having started from a dead stop. What is each cart’s state of motion value and which underwent the greater impulse? If each cart’s impulse underwent the same time interval, which cart underwent the most force? show work so I can understand pleaseBefore a collision, Cart A has 50 kg m/s of momentum and Cart B has -10 kg m/s momentum. Following the collision, Cart A has momentum of 30 kg m/s, Cart B is moving but you don’t know its momentum yet. What is the total momentum of the 2 car system before the explosion? Show your work. Assuming this system is isolated, what is the total momentum of the 2 car system after the explosion? What is the momentum of cart B after the explosion? If Cart B has a mass of 5 kg, how fast is cart B moving?
- Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. Thank you. 13. A ball of mass m, is stationary when a ball of mass 2m collides with it travelling with a speed of v. If the collision between the 2 balls is completely inelastic, show that the final velocity of the balls is 2/3 v.Please make the solution and final answer handwritten. Thank you! Rate will be given A car of mass 1,621 kg collides with a wall. The initial speed of the car is 16.4 m/s. After collision, the car bounced in the opposite direction at a speed of 4.6 m/s. If the collision lasted for 176 ms, what was the average force in newtons exerted on the car by the wall? Express your answer in two decimal places with units of Newton.Two ants, Xavier and Yvonne, move from point a to point b on the figure below. Xavier takes path X; Yvonne takes path Y. Even though their paths are different, they both arrive at point b at the same time. Using a ruler and the fact that it took both of them 4.93 seconds to go from point a to point b, calculate both the speed and the velocity (in cm/s) for both Xavier and Yvonne and enter these values into the table. Then, in words, tell me: how do their speeds compare? How do their velocities compare?

- ONLY question 2 b) so what I would like you to do is read the questions and read the feedback and fix my answers thats all here is the question : Here is the feedback : You still did not take into consideration that the combined masses are moving when the spring is compressed. Find speed of combined mass at maximum compression using Momentum equation PTI = PTF and then use Energy Equations to solve for the spring constant. Ek1 + Ek2 = EkT + EE Where EE is the elastic energy stored in the spring. Then use EE = 0.5kx2 to solve for k here is my answer : fix it correctly and give me the final answer :A sled with rider having a combined mass of 130 kgkg travels over the perfectly smooth icy hill shown in the accompanying figure.(Figure 1) How far does the sled land from the foot of the cliff? Express your answer in meters. d=________________mplease answer all parts. for algerba work, show symbolic answer not numerical. thank you!
