Question

The robot uprising begins tomorrow! A robot stands on the roof of Boston Dynamics

(20.0m tall building). The robot practices for the big day by throwing a mannequin with a velocity

of magnitude 25.0m/s at an angle of 37.0 degrees above the horizontal. You can ignore air resistance,

but you can’t ignore the cold, passionless logic of our soon-to-be new overlords. Calculate:

(a) The maximum height above the roof reached by the mannequin.

(b) The magnitude of the velocity of the mannequin just before it strikes the ground.

(c) The horizontal distance from the base of the building to the point where the mannequin strikes

the ground.

(d) Convert the answer in part b to mph. Does that speed sound like one that would ensure the

uprising is successful?
