If raindrops are falling vertically at 9.10 m/s, what angle from the vertical do they make for a person jogging at 2.55 m/s

What is the most useful equation for electric power?

What is the coefficient of kinetic friction μk between the block and the tabletop?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
