A wet socks clinging to the inside of a washing machine drum which is spinning at a speed of 4.7 m/s. The radius of the drum is 30 cm.
(a) As the drum slows down after the washing is done at an angular retardation of 3.25 rad/sec^2 Find the time taken and number of rotations before it stops.
A force F~ = Fx ˆı + Fy ˆ acts on a particle that undergoes a displacement of ~s = sx ˆı + sy ˆ where Fx = 3 N, Fy = −1 N, sx = 5 m, and sy = 2 m. Find the angle between F~ and ~s.
Three warehouse workers are moving a heavy crate from the warehouse to the truck. Looking at them from a top-down view, worker A pulls the box to the North with a force of 10N, worker B pulls the box to the West with a force of 17N, and worker C pulls the box to the South with a force of 20N. The box moves a total of 18m, 20° S of W with the force of the workers. What is the work done by Worker C?
