1) A veterinarian points directly at an angle of 60 to the horizontal at a monkey that is perched on a branch high in a tree. The sleeping projectile is fired at an initial speed of 50 m/s, at which point the monkey lets go of the branch and falls vertically to the ground. If the horizontal distance between the veterinarian and the tree is 100 m, determine:

a) The time required for the projectile to hit the body of the monkey.

b) The height from the floor this impact occurs.
