A rocket is fired at an initial speed v0 = 141.0 m/s from ground level, at an angle θ = 33 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers
(a) Find v0x, the x component of the initial velocity (in m/s)
(b) Find v0y, the y component of the initial velocity (in m/s)
(c) How long (in seconds) does it take the rocket to reach the maximum heght?
(d) How long (in seconds) is the rocket in the air before hitting the ground?
(e) What maximum height (in meters) does the rocket reach above the ground?
(f) What is the range (the horizontal distance) (in meters) the rocket travels before hitting the ground?
Homework Answers
tm2 = 2 tm
Because time taken to reach the maximum height + time taken to reach ground from maximum height = time taken by the flight .

Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as positive y-direction. A....
A baseball is thrown at an angle = 21° above the horizontal with an initial vertical velocity v0y = 9.75 m/s
A baseball is thrown at an angle = 21° above the horizontal with an initial vertical velocity v0y = 9.75 m/s. Use a Cartesian coordinate system with the origin at the baseball's initial position.Part (a) Create an expression for the ball's initial horizontal velocity component, v0x, in terms of v0y, sin(θ), and cos(θ).Part (b) Calculate the initial horizontal velocity component, v0x in m/s. Part (c) Find the ball's initial velocity magnitude, v0 in m/s.
