Amodel rocket is launched from point a with an initial velocity v of 86 m/s. if the rockets descent parachute does not deploy and the rocket lands 104m from a, determine (a)the angle that v forms with the vertical, (b)the maximum height h reached by the rocket, and (c)the duration of the flight.

Explanation:

Given

initial velocity u = 86 m/s

Horizontal distance R = 104 m

Solution

a)

Horizontal range

This angle is made with horizontal so the angle made with the verticle

b)

Maximum height

c)

Time of flight
