QUESTION 3
Suppose you have a 100-kg wooden crate resting on a wood floor. Assume that the maximum force you can exert horizontally on the crate without moving it
is 588 N. If you continue to exert this force once the crate starts to move, what will be the magnitude of its acceleration (in m/s 22 Note: Use Table 5.1
in
Chapter 5 to determine the coefficient of friction for this problem.
Wood on wood static friction = 0.5
Wood on wood kinetic friction = 0.3
