You are watching a stunt-woman set up to be shot from a cannon and (hopefully) over a wall. The cannon will launch her at an angle of 60 ̊above horizontal and a speed of 10 m/s.

As the stunt-woman flies, the horizontal component of her velocity will remain constant, and only the vertical component of her velocity will change.

What is the maximum height wall the stunt-woman can be launched get over with this cannon?

Answer #1

In y direction

VF=0

Vi=10sin60=8.66 m/s

By vf^2=vi^2+2gHmax

Hmax=8.66^2/2*9.8

Hmax=3.826m

    A cannon, located 44.2m from the base of a vertical 29.0m tall cliff, shoots a 15.0kg shell at 40.8° above the horizontal toward the cliff. What must the minimum muzzle velocity be for the shell to clear the cliff edge? The ground at the top of the cliff is level, with a constant elevation of 29.0m above the cannon. How far past the cliff edge does the shell land when the shell is fired at that minimum speed? What is...

    You are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics, you ask one of the archers to shoot an arrow parallel to the ground. You find the arrow stuck in the ground 65.0 m away, making a 2.8 ∘ angle with the ground. Ignore all possible aerodynamic effects on the motion of the arrow. Use 9.80 m/s2 for the acceleration due to gravity. a-For how much time was...
