One of the events in a strength cement block 100 feet. One competitor pulls the block by exerting force of 235 pounds on a rope attached on a rope attached to the block at an angle of 30 degree with the horizontal (see figure). Find the work done in pulling the block. Use the given zero to find all the zeros of the function. Function h(x) = 2x^3 - 7x^2 + 14x + 9 2 - Squareroot 5i x =

Solution

Work will be done by the horizontal component of force.

Horizontal component = 235 Cos 30°

Work done = (235 Cos 30°)*(100)

= 20351.60 ft lb
