You have been employed by the local circus to plan their humancannonball performance. For this act, a spring-loaded cannon willshoot a human projectile, the Great Flyinski, across the big top toa net below. The net is located 4 m lower than the muzzle of thecannon from which the Great Flyinski is launched. The cannon willshoot the Great Flyinski at an angle of 45 degrees above thehorizontal and at a speed of 15 m/s. The ringmaster has asked youto determine a few things in order to make sure the show is bothsafe and entertaining.
a) The x-component of the human cannonball’s initial velocityand final are  _____ m/s.
b) The y-component of the human cannonball’s initial velocityand final are _____ m/s.
c) Now, report the final speed of the human cannonball when hehits the net. The ringmaster will use this information to make sureshe uses a strong enough net, as her circus has had problems withprevious human cannonballs breaking through the bottom of the nets,and it has not been well-received.
d) How long is the human cannonball in the air? The ringmasterwants to make sure the human cannonball is in the air long enoughto impress the audience.
