ue tavorite Darby selecti or by importing your favorites The force acting on a partide varies as in the figure below. (The i marked in inarements of 2.00 m.) x axis (N) x (m) Find the work done by the force as the particle moves across the following distances. (a) from x 0 m to X 16.0 m (b) from x 16.0 m to x 24.0 m -4.834 in orde How is the work that the force does on the particle related to a feature of the Fr vs. x graph? Apply that relation to the graph particle. J (c) from xa o m to x 24.0 m 43.166 x the first two parts of this problem, but because at least You appear to have calculated this answer correctly from your answers to this part is also wrong. JExplanation / Answer
a)) From x = 0 to x = 16 m,
W = Area of upper triangle
= 0.5*b*h
= 0.5*16*6
= 48 J
b)From x = 16 to x = 24 m,
W = Area of lower triangle
= 0.5*(24-16)*-3
= -12 J
c)) From x = 0 to x = 24 m,
Wtotal = 48-12 = 36 J
Q-2)
Vertical velocityis zero
horizontal velocity is vcos(theta)
= 38cos(30)
= 32.91 m/s
KE = 0.5mv^2
= 0.5(0.15)(32.91^2)
= 81.25 joules
