PLEASE I HAVE NO IDEA WHERE TO START
A quarterback is asked to throw a football to a receiver that is 32.1 m away. What is the minimum speed that the football must have when it leaves the quarterback's hand? Ignore air resistance. Assume the ball is caught at the same height as it is thrown.

1. Hmm. Sounds lke a "Hail Mary" pass for 98 yards.

The minimum speed is required when the ball is thrown at a 45 degree angle. (As a separate exercise, see if you can prove that). In that case, the ball travels V^2/g horizontally.

Solve the equation
V^2/g = 32.1 m

to obtain the throw velocity, V, required
