Question
I know parts a,b,c but i do not know d.
![You are pulling a box of mass m along a
frictionless horizontal surface by
exerting a constant force of magnitude F
F
on a rope an angle 0 above the
horizontal, as shown.
m
a) After the box has travelled a distance d, how much work have you done? Your answer
should be in terms of F, 0, and d.
b) If the box was not moving when you started pulling on it, what is the magnitude of the
velocity of the box after you pull it a distance d? Your answer should be in terms of m, F,
0, and d.
c) If the box was not moving when you started pulling on it, what is the magnitude of the
velocity of the box after you pull it for a time t? Your answer should be in terms of m, F,
0, and t.
d) If the magnitude of force you exert is 200 N, the angle 0 is 60 degrees, and it takes
