5. One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching the first snowball, you throw a second one at a low angle timed to arrive at your opponent at the same time as the first one. Assume both snowballs are thrown with a speed of 25 m/s. The first one is thrown at an angle of 70° with respect to the horizontal. (a) At what angle should the second snowball be thrown in order to arrive at the same point as the first? (b) How many seconds later should the second snowball is thrown after the first to arrive at your target at the same time?

Coast Guard rescue swimmers are trained toleap from helicopters into the sea to save boaters in distress. Therescuers like to step off their helicopter when it is “ten and ten,”which means that it is ten feet above the water and moving forward horizontally at ten knots. What are (a) the speed and (b) thedirection of motion as a rescue swimmer enters the water following a ten and ten jump?
A gun fires a shell with a velocity of 600 m/sec at an angle of 45°with the horizontal. Neglecting ail' resistance, (a) determine the range of thisgun, (b) determine the maximum height reached by the shell, and (c) determinethe time of flight of this shell on level ground.

A cannon is fired at an angle of 44°44° with the horizontal. If the cannonball has an initial velocity of 724 feet per second, how far (horizontally) will the shot travel? Assume the initial height of the projectile is 0 feet, and neglect air resistance.
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.335 m above his mouth. What is the minimum speed at which the archer fish must spit?
A quarterback passes the football downfield at 19.0 m/s. It leaves his hand 1.70 m above the ground and is caught by a receiver 36.0 m away at the same height. What is the maximum height of the ball on its way to the receiver? so y0 = 1.7m x(t) = 36m , i guess i will need angle and t to get the answer, but i have no idea how to find them
