A popular pastime is to see who can push an object closest to the edge of a table without its going off. You push the 100 gram object and release it 1.50 meter from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.50 meter to the floor, and lands 35 centimeter from the edge of the table.
If the coefficient of kinetic friction is 0.400, find what is the object speed as you released it?
A hawk is flying horizontally at 17.0m/s in a straight line, 160 m above the ground. A mouse it has been carrying struggles free from its grasp. The hawk continues on its path at the same speed for 2.00s before attempting to retrieve its prey.
A proton moves at a speed of 995 m/s in a direction perpendicular to a magnetic field with a magnitude of 0.76 T
two point charges lie along the y-axis. a charge of q1 -7 microc is at y 6.0 m and a charge of q2 -5.5 microc is at
Charges of 3.0 nC, -2.0 nC, -7.0 nC, and 1.0 nC are contained inside a rectangular box with length 1.0 m, width 2.0 m, find the electric flux through the surface of the box

In recent years, a number of nearby stars have been found to possess planets. Suppose, the orbital radius of such a planet is found to be 3.1 1011 m, with a period of 1140 days
A daredevil on the motorcycle leaves the end of a ramp with a speed of 36.0 m/s. If his speed is 34.20 m/s while he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance. In meters
