Block A has a mass of 6kg and block B has a mass of 3kg. Block B is falling, as block B is falling it accelerates to the right at 1.32m/s^2, the coefficient of kinetic friction between block A and the surface is is 0.3. Assume the connecting rope has negligible mass. The pulley's mass is only to redirect the chord. a.) Find force exerted by the surface on block A

b.) Find the frictional force

c.) Find the tension in the chord

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
