A Force Fx acts on a particle that has a mass of 1.5 kg. the force is related to the position x of the particle by the formula fx = Cx^3, where C = 0.5 if x is in metersand Fx. is in Newtons.
a.) What are the SI units of C?
b.) Find the work done by this force on the particle when the particle moves from x = 1.0m to x = 2.5m?
c.) At x = 2.5m the force points opposite the direction of the particle's velocity (speed is 12). what is its speed at 1.0?
for part a, i got N/m^3 which i got it right.
for part b, i got 4.8, which i also got it right.
i need help with part "c".
