关于加速度、牛顿运动定律的一道物理题
An object of mass m1 hangs from a string that passes over a very light pulley P1 as shown in the figure.The string connects to a second very light pulley P2.A second string passes around this pulley with one end attached to a wall and the other to an object of mass m2 on a frictionless,horizontal table.(a )If a1 and a2 are the accelerations of m1 and m2,respectively,what is the relationship between these accelerations?Find expressions for(b)the tensions in the strings and(c)the accelerations a1 and a2 in terms of the masses m1 and m2,and g.
