The motion of the pistion o fan automobile engine is SHM
a) if the stroke of an engine (twice theamplitude) is 4 in. and the angular velocity is 3600 rev/mincompute the acceleration of hte pistion at the end of itsstrokeb)if the pistion weight is 1 Ib what restoring force must beexerted on it at this point ?c) what is the velocityof the pistion in miles per hour at the midpoint of the stroke.
A string is wrapped around a pulley of radius 3.05? , and a weight hangs from the other end. What's the angular acceleration of the pulley
A simple pendulum has a length of 0.70 m and a mass of 0.75 kg. Calculate the quantum number for the pendulum
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 7.50 m/s at an angle of 25.0° below the horizontal. It strikes the ground 5.00 s later. (a) How far horizontally from the base of the building does..
High-speed stroboscopic photographs show that the head of a 260 g golf club is traveling at 54 m/s just before it strikes a 46 g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 44 m/s. Find the speed ..
