A basketball star covers 2.65 m horizontally in a jump to dunk the ball. His motion through space can be modeled precisely as that of a particle at his center of mass. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.95 m above the floor and is at elevation 0.910 m when he touches down again. (a) Determine his time of flight (his "hang time" (b) Determine his...

The OntarioTech rowing team is moving along at a steady speed of 17.86 m/s. The cox issues an order to increase the rate of speed of the boat and the boat uniformly accelerates to reach a final speed of 41.1 m/s. If the boat traveled a distance of 53 m before reaching the final velocity, what was the boat’s acceleration over that distance? An airplane accelerates down a runway at 13.7 m/s2 for 12.1 s until it finally lifts off...

Simone, a 47 kg gymnast, is performing the last tumbling pass of
her floor routine. The tumbling pass involves running as fast as
possible then jumping into the air to complete a double layout with
a twist (this exact maneuver, the double layout with a twist, is
not important, but a photo is provided on Canvas to show you what
this maneuver is). The instant before she jumps into the air, her
center of mass (COM) is 0.90 m above...
Suppose the vertical height h that Supergirl can jump after she compresses her tendons a distance...
Suppose the vertical height h that Supergirl can jump after she compresses her tendons a distance x1 (beyond her unstretched length) is 25m. How high would she jump after she has compresses her tendons an additional 10% more than before (that is a distance 1.10x1 beyond her unstretched length)? A block of mass 3kg slides along a horizontal table with speed 10m/s. At x = 0 it hits a spring with spring constant 10N/m and begins to experience a friction...

I need help with the last three questions
the Loop A mass m -82 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R 7.8 m and finally a flat straight section at the same height as the center of the loop (17.8 m off the ground). Since the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it...

1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
