Find the torque on the meter stick for each situation. Ignore the mass of the meter stick. Use L = 1 meter and g=10m/s. a. 1 N mb. 2 N mc. 3 N md. 4 N me. 5 N mf. 6 N mg. 7 N mA = 500gB = L/2 1000gC = 750gD = L/2 1000g 500gE = 1000gF = L/2 500g 500gG = L/2 500g

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.

Acar drives straight down toward the bottom of a valley and up the other side on a road whose bottom has a radius of curvature of 115 m. at the very bottom, the normal force on the driver is twice his weight. at what speed was the car traveling?
