Three different expressions for the centripetal acceleration as a function of time are given for an object moving in a circle. In each case, determine the graph that best represents the variation of the tangential acceleration with time. The vertical axes represent the tangential acceleration, the horizontal axes represent time, the arrows indicate the positive direction, and the variables A, B, and C all represent positive constants.

A HeNe (Helium-Neon) laser has a beam power of 5.00 mW at a wavelength of 656 nm. Assume the beam is focused by a lens to a circular spot whose effective diameter is 15 wavelengths of the light.
Given a pair of forces, one with magnitude 27.3 N at an angle of 24 degrees clockwise from the +x direction and the other with magnitude 15.7 N exactly in the +x direction: Find the direction of the acceleration
You put an 8 cm3 block of ice (the ice is at 0 oC) into your 20 oCliter Coke (similar heat capacity as water). All of the ice melts and resulting fluid comes to equilibrium with no heat loss. What is the temperature of the fluid?
