Hello, I need some help with physics, thank you!

Question 1 1 Point A cannon is mounted on wheels and is at rest. It shoots a 5.8 kg ball with a velocity of 7.1 m/s. The cannon has a mass of 6.9 kg. What is the recoil velocity of the cannon? Leave your answer to 1 decimal place. Add your answer Question 2 2 Points You are coding a 2D NFL game. The player with the ball is 97 kg and is running at (1, 35) px/s. The opponent is 93 kg and runs at (23, 4) px/s to make the tackle. What is the magnitude of the final 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 104 kg and is standing still. Player 2 shoots a fireball which successfully damages the other player and delivers an impulse of 1444 kg m/s. How fast will the victim go flying?
