Homework Answers
A] Let the tension be T and acceleration be a, by force equation on two blocks,
m2g - T = m2a
T = m1a
adding both, m2g = (m1+m2)a
a = m2g/(m1+m2) = 1*9.8/[1+7.9]
= 1.1 m/s^2
B] a = m2g/(m1+m2)
for largest a, m1 = 0 kg
C] a = g = 9.8 m/s^2

2. Atwood's Table with Two Hanging Masses You have table of width L, masses m1, m2, and m3, two frictionless pulleys, and ideal string. Placing m2 on the table, you attach a bit of string to mass m1 the left pulley, to the left side of m2. Similarly, you hang mass m3 from the right side of m2 using the pulley on the right side of the table. The coefficient of friction of the table is mu. The acceleration of...

Two masses are connected by a string over the edge of a table by a frictionless pulley. The horizontal table holds the second mass m2, and the first mass m1 is suspended off of the pulley. Assume the table is frictionless unless specified otherwise. For each part of this problem: Draw free body diagrams of both objects and write down equations for Newtons second law for both masses.

2. Consider two masses conne two masses with friction". Assume that there is a significant friction between mass m, and the supporting, horizontal surface. What must be the value of the coefficient of kinetic friction u. for the two masses to move at a constant velocity? The constant velocity means that the acceleration a 0. Derive the formula for u, relative to masses m, and m. Remember that the condition for constant velocity is that the sum of forces acting...

Torque and Angular Acceleration Learning Goal: To understand and apply the formula τ= Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law. Fnet =ma, where Fnet is the net force acting on the particle. To find the angular acceleration a of a rigid object rotating about a fixed axis, we can use a similar formula: Tnet = Ia, where Tnet=∑T is the net torque acting on the object...
