A cylinder is dropped from rest at a height of 3.71 m above the ground. How...
At a height h = 44.0 m above the ground a rocket is fired at an initial speed v0 = 168.0 m/s at an angle θ = 27 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component...

(a) A ball is dropped from rest from an initial height h above the floor. It then bounces several times. Draw graphs the position y(e), velocity v, (e) and acceleration ay () of the ball for two complete bounces (hitting the ground t for py Ct) ay (t) (b) If the ball is released from rest at a height h the ground? 1.50 m above the floor, how fast is the ball moving when it reach (c) If the ball...
The height of a helicopter above the ground is given by h = 2, 75t3, where h is in meters and t is in seconds. At t = 2.10 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground? [HINT: Make a list of important clock readings. Make a motion map for the bag before and after it is dropped. Make a list of known quantities. How fast is the bag going...
The height of a helicopter above the ground is given by h-2-95t3, where h is in meters and t is in seconds. At t = 1.65 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground? [HINT: Make a list of important clock readings. Make a motion map for the bag before and after it is dropped. Make a list of known quantities. How fast is the bag going before it is...
The height of a helicopter above the ground is given by h = 2.80t3, where h is in meters and t is in seconds. At t = 1.90 s, the helicopter releases a small mailbag. (a) How long after its release does the mailbag reach the ground? (b) With what velocity does the mailbag hit the ground?
