a cart pulled by a mass hanging off a pulley. will the cart's acceleration be equal to g?

a laboratory-cart is being pulled along a table by a mass that is hanging off a pulley at the end of the table. will the cart's acceleration be equal to the acceleration due to gravity?

Update:

!! PS: the solution should lie in 'simple' kinematics concepts !!

    No.

    a = g*[1 - (1+µ)/(1+M/Mc)]

    where µ = coefficient of friction of the table, M = hanging mass and Mc = cart mass.

    You can see that the expression in the brackets will always be less than 1.0
