A U-shaped tube, open to the air on both ends, contains mercury. Water is poured into the left arm until the water column is 12.7 centimeter deep.
Find how far upward from its initial position does the mercury in the right arm rise?
Can someone help me solve problem 181, chapter 12 from Engineering Mechanics statics and dynamics, 13th edition. The question is, simply, r = 4sin(2theta), theta = (3t^(3/2))rad. Determine the velocity and acceleration when theta = 60 degrees.
