Create a Catapult that can launch a ball 50 m
Begin by constructing a three bar linkage that has two bars with the ability to move and one fixed to stay in place.

Make sure to record the length of the bars, it will affect how far the ball travels
Using Create a simulation in SimScape as a guide, design a simulation of a catapult launch in which you can change the input of torque acting on the arms.
Using Create a simulation in SimScape as a guide, design a simulation of a catapult launch in which you can change the input of torque acting on the arms.
Assume the ball is being released from the end of the arm furthest from the fixed point, and disregard the effect of the mass of the ball on the arms.
Read the results of the simulation and choose a time to release the ball. At this time record the angles of the arms and their angular velocities.
Read the results of the simulation and choose a time to release the ball. At this time record the angles of the arms and their angular velocities.
From the data recorded, the height the ball is being released from, the angle it is released at, and the initial velocity of the ball at release are all necessary to find the distance the ball will travel.
