A projectile is fired from ground level at time t=0, at an angle θ with respect to the horizontal. It has an initial speed v0 Assume the ground is level. Express answers in parts a - d in terms of v0 θ and g (the magnitude of the acceleration due to gravity.)
a) Find the time, tH, it takes the projectile to reach its maximum height H
b) Find tR, the time at which the projectile hits the ground after having traveled through a horizontal distance R
c) Find H, the maximum height attained by the projectile.
d) Find the total distance R(range) traveled in the x direction by the projectile.
