6. A crane lifts a 3000kg block with a chain vertically upward. a. The resting block has been lifted upward with a uniform acceleration of 3.5m/s for 4 seconds. Find the tension force from the chain. b. The block is now lifted with balanced vertical forces for another 15 seconds. Calculate the tension force from the chain within this duration c. The block then starts to accelerate for another 4 seconds in the opposite direction with a magnitude of 2.5m/s". Compute the tension force from the chain within this duration

Fluid Force. A swimming pool is filled with fresh water to a depth of 7 feet measured at the deep end. There is not enough water in the pool to reach the shallow end. Assume that the pool is constucted using right angles, except where the bottom of the pool meets the end walls. Use Ah for the height of a typical strip across the face of the wall. 6. The weight density of water is 62.4 lb/ Your anwers should have units: pounds. 4 ft 18 ft 24 ft Declare your variable(s) here. Show your reasoning below: a) find the force on the typical horizontal strip (red) ? b) write an integral for the total force on the (left) wall of the pool
