Chapter 2, Problem 2C
Two forces, one equal to 15 N and another equal to 40 N, act on a 50-kg crate resting on a horizontal surface as shown in Figure 2.55.
(a) What is the net horizontal force on the crate?
(b) What is its horizontal acceleration?
(c) If the crate starts from rest, what is its horizontal speed after 5 s?
(d) How far has the crate traveled along the surface in this time?
