Solved: In Fig. 7-47a, a 2.0 N force is applied to a 4.0
Chapter , Problem 72(choose chapter or problem)
In Fig. 7-47a, a 2.0 N force is applied to a 4.0 kg block at a downward angle (J as the block moves rightward through 1.0 m across a frictionless floor. Find an expression for the speed vf of the block at the end of that distance if the block's initial velocity is (a) o and (b) 1.0 mls to the right. (c) The situation in Fig. 7-47 b is similar in that the block is initially moving at 1.0 mls to the right, but now the 2.0 N force is directed downward to the left. Find an expression for the speed vf of the block at the end of the 1.0 m distance. (d) Graph all three expressions for vfversus downward angle (Jfor (J = 0 to (J = 90. Interpret the graphs.
