Part A - 

A ball is thrown straight down with an initial speed of 2.4 m/s from a height of 75 m. What is the position of the ball after 2.6 s, in meters? Use g = 10 m/s2.

Part B -

Two big bugs, Buzz and Crunchy each of mass 0.60 kg, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 4.3 m and it spins with an angular speed of 90 degrees/second. What is the magnitude of the net force on Crunchy, in Newtons?
