Starting from rest, a 88-kg firefighter slides down a fire pole. the average frictional force exerted on him by the pole has a magnitude of 800 n, and his speed at the bottom of the pole is 3.2 m/s. how far did he slide down the pole?

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
