Aperson flings a nickel off of the willis tower (h = 324 m) with a downward velocity of magnitude v0 = 6 m/s. a. calculate the time t, in seconds, that it takes for the nickel to fall.
b. find the speed at which the nickel strikes the ground vf, in meters per second, using the initial velocity, v0, and the drop distance, h.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
