A 75 kg man holds a 25 kg uniform rod at an angle 60° as shown. He leans backward at an angle 60° so that his centre of gravity (centre of mass) 'P' is 0.5 m to the right of his feet. The length of rod is : Rod hand ΣΤΟ Vcds6o 2 1560 n Centre of XP gravity of man 5 feet 360º 60% rough 05m" ground (B) 6 m (D) 8 m (A) 4m (C) 7 m 1

7. Joe, a pole-vaulter, is holding a vaulting pole parallel to the ground. The pole is 5 m long. Joe grips the pole with his right hand 10 cm from the top end of the pole and with his left hand 1 m from the top end of the pole. Although the pole is light (its mass is only 2.5 kg), the forces that Joe must exert on the pole to maintain it in this position are large. How large...

A 75 kg man running at 2.5 m/s jumps off a roof that is 3 m high. As he hits the ground, he tucks into a ball and rolls without slipping to break his fall. Modeling the man as a solid sphere of a radius 0.75 m, assuming no rotational motion before he hits the ground, and ignoring any effects of him tucking into a ball, what is his center of mass velocity on the ground?

A man holds a 182-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force M, which is applied perpendicular to the forearm. The forearm weighs 19.3 N and has a center of gravity as indicated. Find (a) the magnitude of and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone to...
