Newton’s Laws Worksheet
Three blocks that are connected by cables (that don’t stretch) are pulled across a
frictionless surface as shown below. Turn this problem in at the beginning of the next
lecture.
a. Draw a free-body diagram treating the three objects as one large object.
b. Sum the forces on this large object to obtain the acceleration of the system.
c. What would happen if the acceleration of each object were different?
d. Draw a free-body diagram for each object.
e. Sum the forces in the x-direction for each object.
