A crane lifts a 3 tons block with a chain vertically upward. a. The resting block has been lifted upward with a uniform acceleration of 2m/s for 3seconds. Find the tension force from the chain. b. The block is now lifted with balanced vertical forces for another 10 seconds. Calculate the tension force from the chain within this duration. c. The block then starts to accelerate for another 2 seconds in the opposite direction with a magnitude of 1.5m/s. Compute the tension force from the chain within this duration.
