A small ball is attached to one end of a spring that has an unstrained length of 0.215 m. The spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 3.76 m/s. The spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0132 m. By how much would the spring stretch if it were attached to the ceiling and the ball allowed to hang straight down, motionless?

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.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
