4. Two people carry a beam of length L=7.75 m and weight 385 N. The person on the left, Sam, carries the beam 1.00 m to the right of the left end of the beam. The person on the right, Joe, carries the beam 2.00 m to the left of the right end of the beam. a. Determine the force Sam exerts on the beam. Sam and Joe stop. The beam is horizontal, and at a height 0.900 m above the ground. Sam's hand slips and he drops the beam. Joe is able to hold the beam so that at his position the beam remains 0.900 m above the ground while the end of the beam closer to Sam falls to the ground. b. Calculate the speed of the end of the beam just as it reaches the ground.
