Hello, I need some help with physics. Topic: momentum and elasticity. Thank you!

Question 1 1 Point E A cannon is mounted on wheels and is at rest. rt shoots a 3.8 kg hall with a velocity of 8.9 mis. The cannon has a mass of 5 kg. What is the recoil velocity of the cannon? Leave your answer to 1 decimal place. Add your answer Question 2 You are coding a 2D NFL game. The player with the ball is 86 kg and is running at [1. 31} pads. The opponent is 94 kg and runs at {25. 4} pxr's to make the tackle. What is the magnitude of the nal velocity vector (the scalar speed. so just a number} of both players together immediately after the tackle? Leave your answer accurate to 2 decimal places. Add your answer Question 3 1 Point You are coding a game like Street Fighter. Player 1 has a mass of 'l '11 kg and is standing still. Player 2 shops a reball which successfully damages the other player and delivers an impulse of 1394 kg mfs. How fast will the victim go ying? Leave your answer to 1 decimal place. Add your
