Four people participate in a rope competition. Two of them pull the rope right, exerting forces of magnitude 330 N and 380 N . The other two pull left, exerting forces of magnitude 360N and 400N .

Part A

What is the sum of the forces exerted on a short section in the middle of the rope?
Express your answer to two significant figures and include the appropriate units. Enter positive value if the direction of the force is to the right and negative value if the direction of the force is to the left..

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
