A helicopter is traveling at 54 m/s at a constant altitude of 100 m over a level field. If a wheel falls off the helicopter, with what speed will it hit the ground? Note: g = 9.8 m/s2 and air resistance is negligible.
a. 40 m/s
c. 60 m/s
b. 50 m/s
d. 70 m/s

Question 2

A baseball is thrown by the center fielder (from shoulder level) to home plate where it is caught (on the fly at eye level) by the catcher. At what point does the magnitude of the vertical component of velocity have its maximum value? (air resistance is negligible)
a. just after leaving the center fielder's hand
b. just before arriving at the catcher's mitt
c. at the top of the trajectory
d. the magnitude of vertical component of velocity is constant
