Calculus
vel = at where t is in hrs, and a is in miles/hrs^2 then s = (1/2)at^2 where s is the distance in miles when v = 160 at=160 t = 160/a when s= .7 (1/2)a(160/a)^2 = .7 a = 18285.7 miles/hrs^2 so what time is liftoff? 160 = 18285t t = .00875 hrs or 31.5 seconds check: at t= 0, v...

Pretty silly question. The official mass of a major league baseball is 0.145 kg. No pitcher has ever thrown a baseball 200 km/h. Not even Sandy Koufax. You can derive a baseballmass from the numbers you were given by equating the kinetic energy of the baseball to the work done...
