1. A car accelerates uniformly from rest at +5.3m/s^2. calculate the speed of the car when it has traveled 1.5 meters 2. The acceleration due to gravity on the moon's surface is 1.62m/s^2. Find the time it takes for an object dropped from 10.0 meters to reach the ground. (note: the moon has no atmosphere)

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
