1- A professional skier reaches a speed of 56 m/s on a30degree ski slope. Ignoring friction, what was the minimumdistancealong the slope the skier would have had to travel,starting fromrest. 2- A cannon of mass 1500kg fires a 10 kg shell with a velocityof 200m/s at an angle of 45degrees above the horizontal.Find therecoil velocity of the cannonacross the level ground.3- A bucket in an old well is hoisted upward by a ropewhichwinds up on a cylinder having a radius of .050 m. How manyrev/smust the cylinder turn if the bucket is raised at a speed of0.15m/s.
