An object is launched with a speed v0 = 80.0 m/s and with an
angle α0 = 60º with respect to the flat surface from which it was
launched at a place where g = 9.80 m/s^2.
a) Calculate the position (x, y) of the object when t =
4.00s.
b) Calculate the magnitude and direction of its velocity when t =
4.00s.
c) Determine the time at which the object reaches its maximum
height and the value of said maximum height.
d) Determine the maximum horizontal distance (reach) of the
object.

Show that for an object launched with an initial angle, α0, and initial velocity, V0, from X0 = y0 at t = 0, its projectile motion will trace out a parabola of the form y = Ax – Bx2 on a y versus x graph. Here, A and B are constants of the motion related to initial conditions. Explicitly show the expressions for constants A and B, as well.

A rocket has an initial speed of 80.0 m/s when it is launched. It accelerates upward at a rate of 4.00 m/s2. (a) When does the rocket reach a height of 1000 m? (b) What is the rocket’s speed at that time? (c) At this point, the used first stage of the rocket is disconnected from the rocket. After this, the only force acting on the first stage is gravity. What is the maximum height reached by the first stage?
