Physics

Four point masses are arranged as follows: m1 = 5.76 g at(0,19.6 cm), m2 = 2.25 g at (19.6, 0) cm, m3 = m1 at (0,-19.6) cmand m4 = m2/.49 at (-19.6, 0) cm. These are all immovable

a) In unit vector notation, what is the net gravitational forcefrom them on a point with mass m5 = 2.56 g at the origin?

b) If m5 was free to move and released from rest what will itsspeed be after travelling 9.8 cm?

c) Imagine a new configuration where m2 has been removed. Whatwould then be the new answer to part b?
