A particle of mass

0.50\,\text{kg}

moves along the positive

x

-axis under the influence of a position-dependent force

F(x)=3x^{2}\,\text{N}

, where

x

is in metres. The particle is released from rest at the origin. (i) Calculate the work done on the particle as it moves from

x=0

x=2.0\,\text{m}

. (ii) Determine the speed of the particle at

x=2.0\,\text{m}
