Question
Assume the three blocks (m1 = 1.0 kg, m2 = 2.0 kg, and m3 = 4.3 kg) portrayed in the figure below move on a frictionless surface and a force F = 41 N acts as shown on
the 4.3-kg block.
F
(a) Determine the acceleration given this system.
(b) Determine the tension in the cord connecting the 4.3-kg block and the 1.0-kg blocks.
(c) Determine the force exerted by the 1.0-kg block on the 2.0-kg block.
Step 1
(a) If we consider the system to consist of all three blocks plus the connecting rope, the total mass of the system is
kg.
mtotal = m1 + m2 + m3 =
The only horizontal external force acting on this system is the applied force directed toward the right, which Is chosen as the positive x-direction. Thus, Newton's second
law gives
3(-)
1 kg - m/s?
1 N
