You throw a 0.5 kg rock upward from your hand (which is 1 m off the ground when the rock leaves it). The rock rises to a maximum height of 2.5 m and then falls past your hand to the ground. From the moment you let it go until the moment just before it lands, what can you say about the work that gravity does on the rock? Group of answer choices a. Gravity does negative net work on the...

6. [10 points) For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Work with the approximate value g = 9.8 m/s2 for the Earth's gravitational acceleration. Consider the following experiment. The Leaning Tower of Pisa is known worldwide for its nearly four- degree lean. The height of the tower is 55.86 meters from the ground on the low side, and 56.67 meters on the high side....

Now let's consider the resistance of speaker wire. Suppose you're hooking up a pair of stereo speakers, You happen to have on hand some 20-m-Jong pieces of 16 gauge copper wire (diameter 1.3 mm); you use them to connect the speakers to the amplifier. These wires are longer than needed, but you just coil up the excess length instead of cutting them. What is the resistance of one of these wires? To improve the performance of the system, you purchase...

Hand In Problem 2 A solid globe of mass M and radius R can rotate about its axis. A block of mass m is attached by a massless-string/pulley system as shown. As the block falls it causes the globe to spin. If the block starts at rest, at what speed does the block hit the ground after it falls a distance h? ' State your answer in terms of the given variables: M, R, m, h and g. Solve this...

Use the worked example above to help you solve this problem. A merry-go-round modeled as a disk of mass M 7.00 x 101 kg and radius R 2.40 m is rotating in a horizontal plane about a frictionless vertical axle (see figure). (a) After a student with mass m 86.0 kg jumps onto the merry-go-round, the system's angular speed decreases to 1.95 rad/s. If the student walks slowly from the edge toward the center, find the angular speed of the...
