A force Fx acts on a particle that has a mass of 1.5 kg. Theforceis related to the position x of the particle by the formula Fx=Cx^3 where C = 0.50 if x is in meters and Fx is in newtons.
a) what are the SI units of C?
b)Find the work done by this force as the particle moves from x=3.0 m to x = 1.5 m
c)at x = 3.0 m, the force points opposite the direction oftheparticle's velocity (speed is 12.0 m/s)
What is its speed at x = 1.5 m? Can you tell its direction ofmotionat x =1.5 m using only the work-kinetic energytheorem?Explain
