The 1.23kg physics book shown is connected by a string to a 505.0g coffee cup. The book is given a push up the slope (call this direction positive) and released with a speed of 2.21m/s. The coefficients of friction are μs = 0.450 and μk = 0.221. a) What is the acceleration of the book if the slope is inclined at 30.0°?

b) How far does the book slide before it has zero speed?

1. how to locate the image in converging(concave) mirror and diverging (convex) mirror with salt. 2. how to locate the image in a converging (convex) lens and diverging (concave) lens with salt.

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

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
