Homework Answers
ONE QUESTION AT A TIME PLEASE AS PER THE RULES
-----------------------------------------------
1)
Here are the free body diagrams
The diagram on the left is for hanging mass and diagram on the right is for mass on table.
For hanging mass, we have
T - m1g = m1a ---------- (1)
For mass on table, we have
F - T = m2a --------- (2)
combine (1) and (2)
a = F - m1g / m1 + m2
Therefore,
put in the values,
a = 30 - 3* 9.8 / 3 + 10
a = 0.046 m/s2
and the tension is
T = 29.5 N

I am confused when they say
the "the force down the plane has the sine component and the normal
force and force into the plane have the cosine component." Also
aren't I only suppose to look at a certain component of the weight
force? If you could please label all the forces, their direction,
and whether they would be sine or cosine that would be greatly
appreciated, thank you!

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
