# Question: In a circus act a uniform board length 3 00 m

In a circus act, a uniform board (length 3.00 m, mass 35.0 kg) is suspended from a bungie-type rope at one end, and the other end rests on a concrete pillar. When a clown (mass 75.0 kg) steps out halfway onto the board, the board tilts so the rope end is from the horizontal and the rope stays vertical.

(a) In which situation will the rope tension be larger: (1) the board without the clown on it, (2) the board with the clown on it, or (3) you can’t tell from the data given?

(b) Calculate the force exerted by the rope in both situations.
