Hi all, I can't find a function of this data, since the cart is already in motion. Please help a noobie at physics!! Time is increasing from 0.0 to 2.0 by .1 x (in m) is 5.0 at 0.0 and 49.0 at 2.0 seconds the cart thats moving is 5.0 kg intially traveling at some unknown velocity on a horizontal frictionless surface. Starting at t=0s, a constant force F, is applied for two seconds, after these two seconds the force is no longer applied. so, the question is, Find an equation for position as a function of time that fits the data. Then find an equation for the cart's velocity as a function of time. Any help would be much appreciated!
