Block 1 (15 kg) is located on the surface of a table. A rope pulls on block 1 with a tension of 174.9 N at an angle of 38.96 degrees above the horizontal. The coefficient of kinetic friction between the block and the surface equals 0.4 (Use g = 10 m/s2). What are the forces?

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
