I have a ball that is moving the x or +x direction with net forces acting on the ballin the x or +x direction. Consider the scenario when the ball is moving in the +x direction with increasing speed. What are the ways that net force could be acting upon the ball?

Best ResponseYou've already chosen the best response.1\[p=m*v\] \[\Delta p = F_{net}*\Delta t\]

Best ResponseYou've already chosen the best response.1Only consider events in in the x axis. The velocity is increasing as some rate; therefore the momentum increases at the same rate, and because I can determine the net force from change in momentum over time, net force must be increasing proportionally to the change in momentum. If the velocity increases at a constant rate, then the change in momentum(s) is constant, and hence the net force is constant, i.e. the same at all time intervals. If velocity increase at a different rate, then change in momentum is increasing and hence so is the net force. What could then be happening to the ball?

Best ResponseYou've already chosen the best response.1There could be forces in the x direction. Perhaps I should break down the net force on the ball for each direction via a freebody diagram....brb
