Question

Please correct answers and explanation

1. Two masses, m1 and m2, are connected by a mass-less cord passing over an ideal pulley shown in attached picture. Assume that m1 is moving on frictionless plane.

a. Draw a free body diagram for each mass showing all the forces and acceleration

b. Write Newton's equations for each mass.

c. Show that the formula for the acceleration of the system in terms of m1, and g is given by, a=(m2/m1+m2)g

d. Show that your answer makes for m1=0 or m2=0. Explain why they make sense.

e. How would friction change your answers?

Explanation / Answer

m2(g - a) = m1(g + a)

T = m2g((m1-2m2)/m1) Newtons
c. Show that the formula for the acceleration of the system in terms of m1, and g is given by, a=(m2/m1+m2)g
