Suppose that a 5 kg body slides rightwards along a frictional table where μΚ=0.2. If the body starts with a speed of 1 m/s moving to the right...
a) calculate the work done by friction as the book slides along the first 0.1 m (be clear whether or not the work is positive, negative, or zero).
b) Calculate the velocity of the body at the end of that first 0.1 m stretch.

An experiment is designed to test the relationship between the initial height of a basketball before it is dropped to the height of its rebound bounce. the height of the rebound bounce is measured using a scale positioned behind the ball. in the above experiment, which condition would not be controlled? a). the starting height of the ballb). the surface the ball bounces on c). the type of ball d). the method to measure the rebound height of the ball
