During a siege, you as besieger are to bring down a castle's outer wall using a trebuchet. The trebuchet

is positioned at a distance of 250 m. It releases a boulder with a mass of 30 kg at an initial height of 6

m. The walls of the castle are 25 meters high.

The trebuchet is capable of a maximum launch velocity of 60 m/s

a. b. c. d. Determine an initial release angle and velocity that can impact the walls of the castle.

At what height did the projectile hit the walls of the castle for the parameters you have

chosen?

What is the maximum height and total kinetic energy of the projectile for the parameters you

have chosen?

Estimate the horizontal impact force on the wall if the contact time between the projectile and

t h e wall is 1 s e c o n d .

Note: this is an open ended problem. You are free to determine the parameters of the projectile

launch as long as it achieves the objective of hitting the walls (at any height along the wall).
