The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at vi2 =16.9 m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle ?=48.7° below the horizontal and a speed of vi=37.7m/s. What is the speed of the eagle immediately after it catches its prey? speed: What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike? magnitude of angle:

A block (mass = 5.56 kg) is released from rest at the top of a frictionless ramp. 1.01 seconds after release, the block has a speed of 6.34 m/s. Calculate the angle of the ramp in degrees as measured from the horizontal.

As part of an obstacle course, an athlete must kick a soccer ball into a 1 meter wide and 10 meter deep pit such that the ball hits a target at the bottom of the pit. In practice, a dynamics student that is participating in the race kicks the soccer ball such that the soccer ball will bounce off the far wall of the pit 5 meters below the surface and head towards the target. If the velocity of the ball before striking the wall at point at point A is v4 = 2.6i – 10j m, determine the t-component of the ) after striking the wall. The size of the ball and the target ball velocity vector (in are negligible relative to the dimensions of the pit, the gravity acceleration must be considered as g 10 m and the coefficient of restitution at point A is e =0.35. 5 m t 10 m 1m 三
