we were given the question "a ball is thrown upwards with a starting velocity of 25m/s and the acceleration due to gravity is -9.81m/s^2. At what time(s) will the ball be 3.0m above the starting position" and my teacher said that I got it wrong because when I was using the quadratic formula I...
today in physics class our teacher told us that when we were doing a problem we had to round to the sig digs on each step. This semed like it would make the answer less accurate. Is the the right method to use or not.
And if it is correct why is it done this way?
