Question

When it is 159 m above the ground, a rocket traveling vertically upward at a constant 8.30 m/s relative to the ground launches a secondary rocket at a speed of 12.4 m/s at an angle of 53.0 ∘ above the horizontal, both quantities being measured by an observer sitting in the rocket. Air resistance should be ignored.

Part A : Just as the secondary rocket is launched, what are the horizontal and vertical components of its velocity relative to the astronaut sitting in the rocket? Enter your answers numerically separated by a comma.

Part B:

Just as the secondary rocket is launched, what are the horizontal and vertical components of its velocity relative to Mission Control on the ground?

Hint: You need to use Galileo's equation to find the initial velocity with respect to the ground. Frame A is the ground, Frame B is the first rocket and the object of interest P is the secondary rocket.

Enter your answers numerically separated by a comma.

Part C : Find the initial speed of the secondary rocket as measured by Mission Control. Speed is the magnitude of the velocity vector of the secondary rocket with respect to the ground.

Part D: Find the launch angle of the secondary rocket as measured by Mission Control.

Part E: What maximum height above the ground does the secondary rocket reach?
