Figure shows a smooth track, a part of which is a circle of radius R. A block of mass m is pushed against a spring constant k fixed at the left end and is then released. Find the initial compression of the spring so that the block presses the track with a force mg when it reaches the point P [see. Fig], where the radius of the track is horizontal.
One long wire carries current 20.0 A to the left along the x axis, A uniform electric field is applied to allow this particle to pass through this region undeflected. Calculate the required vector electric field
a satellite has a mass of 100 kg and is located at 2.00x 10^6 m above the surface of the earth. estimate the magnitude of the gravitational force on the satellite
An electric vehicle starts from rest and accelerates at a rate of 1.7 m/s2 in a straight line until it reaches a speed of 27 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops. (a) How much time elapses from start to stop? (..
The earth has a net electric charge that causes a field at points near its surface equal to 150N/C and directed in toward the center of the earth. a) What magnitude and sign of charge would a 60 kg human have to acquire to overcome his or her weig..
A student’s car stalls right in front of a speed bump while she is on her way to physics class. To pull it over the bump, she ties a cable to her bumper and to a nearby tree, and pulls with a force, F, of 77.0 lbs (343 N) at the midpoint in a perpend..
