PHYS 151 Study Guide - Midterm Guide: Friction, Switch, Net Force
Document Summary
The coefficient of static friction us, between table and box is. |v|=v=(2*pi*r)/t ii. iii. iv. (2*pi*7m)/12s v=3. 67 m/s p=m*v: which statement below best describes the direction of the momentum of this atom. Inward towards the center like the diagram dp/dt (perpendicular)=fnet (perpendicular) dp/dt (perpendicular)=(mv^2)/r: a child who mass is 30kg sits on a merry go round at a distance of 3m from the center. The merry go round makes one revolution every 8s. |v|=v=(2*pi*r)/t (2*pi*3m)/8s a. b: v=2. 36m/s d. e. f, 55. 5n is the magnitude of the net force. Tangential like in the diagram: which statement best describes the rate of change of momentum i. ii. i. ii. iii, look at comet problem on beachboard, jack and jill are maneuvering a 3000kg boat near a dock. As the boat moves to position<4,0,2>m jack exerts a force of n and jill exerts a force of <150,0,300>n: how much work does jack do, w= f*. /\r=|f|*|. /\r|*cosdelta ii, w=*<3,0,-1>n*m.
