Two men decide to use their cars to pull a
truck stuck in mud. they attach ropes and
one pulls with a force of 734 n at an angle
of 31◦ with respect to the direction in which
the truck is headed, while the other car pulls
with a force of 1084 n at an angle of 23◦ with
respect to the same direction.

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

You have 80 g of 60oc water and 80 g or 10oc water. what is the final temperature when the two are mixed? explain.

Aparticle is moving around in a circle and its position is given in polar coordinates as x = rcosθ, and y = rsinθ, where r is the radius of the circle, and θ is in radians. from these equations derive the equation for centripetal acceleration.
