Lesson 2
1. A ball is thrown at an initial velocity of V0x = 100 in/sec from a stand that is 100 in. above the ground,
as shown in Figure E2-1. The radius of the ball is 0.1 in., and the material is steel.
(i) Create a dynamic simulation model using Mechanism to simulate the trajectory of the ball. Report
position, velocity, and acceleration of the ball at 0.05 seconds in both vertical and horizontal
directions obtained from Mechanism.
(ii) Derive and solve the equations that describe the position and velocity of the ball. Compare your
solutions with those obtained from Mechanism.
(iii) Calculate the time for the ball to reach the ground. Compare your calculation with the simulation
obtained from Mechanism by defining a termination condition.
