Question

3) A football is kicked at an angle of 60 degrees above the horizontal. To make the field goal it must reach a height of at least 3.048 m above the ground. What is the minimum speed the ball can be kick in order make a field goal?

Answer 1

I will be happy to critique your work or thinking. It is not helpful for you to post several questions under several different screen names.

Answer 2

This is what I got so far by using formaul for maximum height mu^2 sin^2 theta/2g = h
and then mu^2(sin60)^2/2*9.81 = 3.048
so mu = 8.929m/s^2

please let me know if I am on correct path and what am I supppose to do next
