Question
The figure(Figure 1) shows a block (mass ) on a smooth horizontal surface, connected by a thin cord that passes over a pulley to a second block , which hangs vertically.A) Apply Newton's second law to find the formula for the acceleration of the system. Ignore friction and the masses of the pulley and cord.
B) Apply Newton's second law to find the formula for the tension in the cord. Ignore friction and the masses of the pulley and cord.
Express your answer in terms of the variables ma,mb, and appropriate constants.
Explanation / Answer
let vertically hanging block moves downward so mb*g-T=mb*a T-ma*g*sin(angle)=ma*a a=m(mb-masin(angle))/(ma+mb) B) t=mb*(g-a)
