2. I feel dizzy. The long-term benefits of the mining machinery factory are extremely poor. It's suicide to go there. You'd better find another job instead of being the factory director.

3. In the initial state, fangzuming is about 1.5 meters (2 meters) above the ground. According to h = 1 / 2GT ^ 2 (free fall formula), fangzuming should fly 5 meters (5 meters) in 0.6 seconds, approximately 10 meters (10 meters) in 1 second. According to e (kinetic energy) = 1 / 2mV ^ 2 (momentum), fangzuming can be calculated as 70 kg. That is to say, he is forced by 3500 cattle (mechanical units), nearly 350 kg, not energy loss, Jackie Chan has a foot of about 350 kg
hope to adopt
