A 99.5 kg horizontal circular platform rotates freely with no frictions about its center at an initial angular velocity of 1.77 rad/s. A monkey drops a 9.73kg bunch of bananas vertically onto the platform. They hit the platform at 4/5 of its radius from the center, adhere to it there, and continues to rotate with it. Then the monkey, whit a mass of 21.3kg, drops vertically to the edge of the platform, grasping it and continues to rotate with platform. Find the angular velocity of the platform with its load. Model the platform as a disk
A galvanometer with a coil resistance of 14.1 is used with a shunt resistor to make a nondigital ammeter that has an equivalent resistance of 0.755. Find the full-scale current of the galvanometer

An electron has an initial velocity of 1.00 ? 106 m/s in a uniform 9.00 ? 105 N/C strength electric field. How long does it take the electron to come to rest
The intensity of a sound produced by a point source decreases as the square of the distance from the source. What is the maximum distance at which the riveter is still audible
A triangle has its corners located at the points (x,y) = (12.00,15.00), (x,y) = (9.00,8.00) and (x,y) = (0,0). Calculate the area of the triangle
how far is this point horizontally from the end of the ramp. A skateboarder shoots off a ramp with a velocity of 6.2 m/s, directed at an angle of 61° above horizontal. The end of the ramp is 1.5 m above the ground.
If there had been no explosion, the shell would have landed a distance from the mortar. Suppose that air resistance and the mass of the shell's explosive charge are negligible. Determine the distance from the mortar at which the larger piece of th..
