How high to reach terminal velocity
Web20 mei 2011 · If a cat reaches terminal velocity of about 60 mph as stated in all sources, then by using the Acceleration constant g of 9.8 m/sec/sec, the cat will reach terminal velocity in 2.7 seconds or longer. That happens at a minimum of approximately 116 feet or 8 to 10 stories. This would tend to contradict the terminal velocity/relaxation theorists. Web14 jun. 2015 · So at the start of the second time step (t=1ms to t=2ms) the object faces a net acceleration force of 9.8M - k* (9.8E-3)^2 and speeds up to v2= (9.8E-3 + (9.8M - k* (9.8E-3)^2) 0.001) and drag at t=2ms increases to D2 = k …
