Starting from rest, a 10.0kg suitcase slides down a frictionless ramp that is 1.5m high. The suitcase then slides an additional 5.00m along the floor before coming to a stop. Find: 1.Kinetic energy of the suitcase at the bottom of the ramp. 2.The speed of the suitcase at the bottom of the ramp, 3.The work done by the force of friction in bringing the suitcase to a stop.4.The force of friction. 5.The coefficient of friction.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
