. A quarterback throws a football straight toward a receiverwith an initial speed of 20.0 m/s, at an angle of 30.0°above the horizontal. At that instant, the receiver is 20.0 rnfrom the quarterback. In what direction and with whatconstant speed should the receiver run in order to catchthe football at the level at which it was thrown?

Your grandfather is copilot of a bomber, flying horizontally over level terrain, with a speed of 275 m/s relative to the ground, at an altitude of 3000 m. (a) The bombardier realeses one bomb. how far will it travel horizontally between it release and its impact on the ground? neglect the effects of air resistence.(b) Firing from the people on the ground suddenly in capacitates the bombardier before he can call, "Bombs away!" Consequently, the pilot maintains the plane's original of course, altitude,and speed through a storm of flak. where will the plane be when the bomb hits the ground? (c) The plane has a telescopic bomb sight set so that the bobm hits the target seen in the sight at the time of release. At what angle from the vertical was the bomb sight set?
