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. In this problem we are assuming that the ground is
level.
a)Find the time tH it takes the projectile to reach
its maximum height
b)Find tR, the time at which the projectile hits the
ground.
c)Find H, the maximum height attained by the
projectile.
d)Find the total distance R (often called the range)
traveled in the x direction; in other words,
find where the projectile lands.
