Question 3
Two blocks, A and B, of mass m and 3m respectively, are connected through a cable
and a pulley (see figure 3.1). Block A is also attached to a spring, which is fixed to
the ground and has a spring constant k = 50 N/m. Block B is on an inclined plane
forming an angle of 30 degrees with the horizontal line. Block B is released from rest
with no slack in the cable and with the spring not being stretched or compressed.
Assign to m the value in kg of your body weight, then
(a) calculate the distance covered by block B once it stops for the first time;
assume that there is no friction.
(b) assume a kinetic friction force F = 5 N acts on block B and calculate the
distance covered by block B once it stops for the first time.
State any assumptions and comment on your solutions.
