A ball player hits a home run, and the baseball just clears a wall 21.0 m high located 150.0 m from home plate. The ball is hit at an angle of 34.0° to the horizontal, and air resistance is negligible. Assume the ball is hit at a height of 1.0 m above the ground and that upward is positive. (a) What is the initial speed of the ball?

(b) How much time does it take for the ball to reach the wall?

(c) Find the velocity components of the ball when it reaches the wall.
m/s (x-component)
m/s (y-component)

Find the speed of the ball when it reaches the wall.

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?

At what time will the interfering waves have an amplitudeof zero?
