- Write a MATLAB M-file that solves the questions of Position and Velocity of a Free Falling Stone. A stone is dropped from the top of a tall building of 200 meters in height, i.e., the initial position of the object is 200 meters. The two equations used are
h(t) = gt2 + v0t + h0
v(t) = gt + v0
where g is the acceleration due to gravity (-9.81 m/s2), h(t) is the position of the object, v(t) is the velocity of the object. h0 is the initial position of the object, v0 is the initial velocity of the object, t is the time. For a free falling object, v0 is 0. h0 here is 200 meters.
Write MATLAB programs to solve the following problems.
- After 2.00 sec of free fall, what is the position of the stone?
- Find the time t_end when the stone reaches the ground. To calculate the value, you should first figure out the expression for t, when h(t) = 0 and v0 = 0. h(t) = 0 means the stone reaches the ground and the position is zero.
- Plot h(t) and v(t) on the same graph and be sure that you plot them with different line-styles and color. Note that the t is the X-axis vector, which is from 0 to the t_end.
