A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.39 m/s at an angle of 85.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 mabove the table?
30. A quarterback claims that he can throw the football a horizontal distance of 183 m (200 yd). Furthermore, he claims that he can do this bylaunching the ball at the relatively low angle of 30.08 above the horizontal.To evaluate this claim, determine the speed with which this quarterbackmust throw the ball. Assume that the ball is launched and caught at thesame vertical level and that air resistance can be ignored. For comparison,a baseball pitcher who can accurately throw a fastball at 45 m/s (100 mph)would be considered exceptional.
