Consider a setup with a horizontal table, two masses, a string, and a massless, frictionless pulley. Assume the masses are m1=1.8 kg and m2= 1.2kg. Also, assume that uk=0.20 and us=0.30. The masses are released from rest.  a. I claim that there is a sufficient net force to get the system sliding. Do a calculation to show that I am right. Include some written explanation to justify your calculation.  b. If m2 starts from rest at 0.50 m above the ground, how long does it take to hit the ground?

Question

Consider a setup with a horizontal table, two masses, a string, and a massless, frictionless pulley. Assume the masses are m1=1.8 kg and m2= 1.2kg. Also, assume that uk=0.20 and us=0.30. The masses are released from rest. 

a. I claim that there is a sufficient net force to get the system sliding. Do a calculation to show that I am right. Include some written explanation to justify your calculation. 

b. If m2 starts from rest at 0.50 m above the ground, how long does it take to hit the ground?
