1. The problem statement, all variables and given/known data A baseball pitcher is known to throw a pitch with a speed of 105 miles per hour. In how many seconds will the pitch reach the catcher if the mound is 20 meters away? (assume 1600 m in 1 mile) 2. Relevant equations v=d/t 3. The attempt at a solution Idk how to convert yet... I always cheat and use an online one but I will be screwed for the test... So I'm going to give this a try... 105 mi = 168000 m 1 hour = 3600 s 105 mi/h = 46.66 m/s The other part of the question I am totally confuse on. So i'll take the d/v=t? 20/46.66=0.4286s? _____________________________________________________________________________ 1. The problem statement, all variables and given/known data A satellite travels at 4,000 km/hr. If the satellite travels 8 X 10^7 meters as it goes around once, how many hours are required for one orbit? 2. Relevant equations v=d/t 3. The attempt at a solution Honestly, I have never seen a problem with scientific notation except in math. I forgot how to do all that. So this one I honestly confuse on. How can I change that scientific notion to a number? I think that's what I need to do.
