Question

Please show all work and detailed explanation I will rate

An eighteen inch pendulum sitting atop a table is in the downward part of its motion. The pivot point for the pendulum is 30 inches above the table top. When the pendulum is 45degree away from vertical, the angle formed at the pivot is decreasing at the rate of 25degree/s. At what rate is the end of the pendulum approaching the table top at this instant? Hint: Draw a right triangle with one acute angle vertex at the pivot point and the other acute angle vertex at the end of the pendulum. The rate of change of one piece of this triangle is the same as the rate you are trying to find. Make sure that each stated and calculated rate value has the correct sign. Make sure that you use appropriate units when defining your variables.
