Forces and motion

  • #1
Hi,

I am trying to help my brother do this problem but I can't figure it out! can anyone please help me...


A 3.45 kg object is moving in a plane, with its x and y coordinates given by x = 7t² - 3 and y = 4t³ + 3, where x and y are in meters and t is in seconds. Find the magnitude of the net force acting on this object at t = 2.35 s.

thank you so much
