The device called an At-woods machine.if m2 is greatr than m1 an assumng th pulley to be frictionless and massless.1.how far will m2 fall in th time T aftr the system is released? 2.what is th tension in the cord that connect two massess? 3. If m1=5kg and m2=3kg,what is the tension in the cord? 4. What is the time needed for the masses to move 15m from rest?
