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.

Researchers have measured the acceleration of racing greyhounds as a function of their speed; a simplified version of their results is shown. The acceleration at low speeds is constant and is limited by the fact that any greater acceleration would result in the dog pitching forward because of the force acting on its hind legs during its power stroke. At higher speeds, the dog’s acceleration is limited by the maximum power its muscles can provide. a. What is the agent of the force that causes the dog to accelerate?b. If the dog’s mass is 32 kg, what is the average force acting on it during its initial acceleration phase?c. How far does the dog run in the first 4.0 s?
