一道英文物理題目(英文其實很簡單).求高手解答~~~~~~~~~~~~~
A 10-kg block is connected to a 40-kg block.The surface on that the blocks slide is frictionless. A force of 50N pulls the blocks to the right.
a) what is the magnitude of the acceleration of the 40-kg block?
b)what is the magnitude of the tension T in the rope that connects the two blocks?

40kg的木塊的加速度為1m/s^2, 10kg和40kg中間的張力T(tension)是10N. 以下為解釋： 把這兩個物理作為一個系統(tǒng),50N的力對這個系統(tǒng)做功,系統(tǒng)的加速度a=F/m=1m/s^2,則單個物體的加速度跟系統(tǒng)的加速度都為1m/s^2；而對重...
