Answer:

Explanation:

x  = 3t^(3/2)  + 2t^(-1/2)

V = dx/dt  = 3 (3/2) t^(1/2)   + 2(-1/2)t^(-3/2)

=> V = (9/2) t^(1/2) - t^(-3/2)

a = dV/dt = d²x/dt²

=> a = (9/2)(1/2)t^(-1/2)  + (3/2)t^(-5/2)

=> a = (9/4)t^(-1/2)   + (3/2)t^(-5/2)

instantaneous force on the body is proportional to (9/4)t^(-1/2)   + (3/2)t^(-5/2)
