In the design of a timing mechanism, the motion of pin p in the fixed circular slot is controlled by the guide a, which is being elevated by its lead screw. guide a starts from rest with pin p at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 175 mm/s at the halfway point of its vertical displacement. the guide then decelerates at a constant rate and comes to a stop with pin p at the uppermost point in the circular slot. determine the n- and t-components of acceleration of pin p once the pin has traveled 30° around the slot from the starting position.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
