A 9 kg object is given a displacement
∆~s = (4 m) ý + (3 m)ˆ J + (−4 m) k
along a straight line. During the displace-
ment, a constant force of
~ F = (1 N) ý + (−5 N) J + (7 N) k
acts on the object.
Find the work done by ~ F for this displace-
ment.
Answer in units of J.
Find the component of ~ F in the direction of
this displacement.
Answer in units of N.
