Hmmm...so if I apply 100 N of force upward, then F=0 and if F=ma then acceleration also equals 0. So now...the velocity is constant, but not slowed down. So to slow it down so that a=10 (equal to the magnitude of gravity) I need to apply an additional 100 N of force upward, requiring 200N. If...
Mcat Physics Question: A 10 kg. mass is in free fall with no air resistance. In order to slow the mass at a rate equal to the magnitude of g, an upward force must be applied with magnitude:
0 N, 10 N, 100 N, or 200 N.
I solved if F=mg then F=10*10 or 100 N downward force. Therefore an...
