There are two particles (1 and 2) that are moving around in space. The force that particle 2 exerts on 1 is given by:

F21(t)=Fx*e^−(t/T)i^ + Fy*sin(2πt/T) j^

Where the parameters have the values:

Fx = 13.4 N

Fy = -84.2 N

T = 74 s

tf = 140.46 s

Find the average force from 1 on 2 from t = 0 until t = tf

Find the average force from 2 on 1 from t = 0 until t = tf
