. 27cp111 – Assume that the three blocks portrayed in the picture at
the right move on a frictionless surface and that a 42-N force acts as
shown on the 3-kg block. Determine (a) the acceleration given this
system. (b) the tension in the cord connecting the 3-kg block and
the 1-kg block, and (c) and the force exerted on the 1-kg block on
the 2-kg block.

1. 62cp115 – Three objects are
connected by light strings as shown at
the right. The string connecting the 4 –
kg object and the 5-kg object passes
over a light frictionless pulley.
Determine (a) the acceleration of each
object and (b) the tension in the two
strings.
