Q1. A box slides down a ramp between a delivery area and soring area. You must determine the angle this ramp should have with the horizontal direction so that a 500 pound box takes 5.0 seconds to slide down the ramp starting from rest at the top. While the box arrives at the bottom of the ramp the speed should be 10 ft/s. friction is neglible.

Q2. A 18 V battery is connected to a 2.50 ? resistor in a rigid rectangular loop of wire measuring 3.13 m by 1.09m. As shown in the figure, a length l = 1.09 m of wire at the end of the loop extends into a 2.18 m by 2.18 m region with a magnetic field of magnitude 4.813 T, directed into the page. What is the net force on loop?
