A cement block accidentally falls from rest from the ledge of a 55.2-m-high building. When the block is 12.2 m above the ground, a man, 1.80 m tall, looks up and notices that the block is directly above him. How much time, at most, does the man have to get out of the way

ill do it for 100, also this isnt 80 its 40

the right answer is 0.3 meters per second

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
