A projectile is fired with a velocity of 980 m/s at an angle of 30 degrees above the horizontal from the top of a hill that is 40.0 m above the flat land below. The projectile just barely passes over a wall of height h = 4.50 m (The wall is not on the hill).
a.) Draw a properly labeled sketch of the problem
b.) Calculate the time at which the projectile passes over the wall.
c.) Calculate the horizontal distance from the top of the hill to the wall.
d.) Calculate the velocity of the projectile as it passes over the wall.
