Part A Firemen are shooting a stream of water at a burning building using a high-pressure hose that shoots out the water with a speed of 25.0 m/s as it leaves the end of the hose. Once it leaves the hose, the water moves in projectile motion. The firemen adjust the angle of elevation a of the hose until the water takes 3.00 s to reach a building 45.0 m away. You can ignore air resistance; assume that the end of the hose is at ground level. Find the angle of elevation a. a = Submit Request Answer Part B Find the speed of the water at the highest point in its trajectory. v = m/s Submit Request Answer Part C Find the magnitude of the acceleration of the water at the highest point in its trajectory. Πν ΑΣφ ? a = m/s?
