A 1.5kg dynamics cart is fastened by a horizontal cord over a pulley at the edge of a table to a mass of 0.50 kg. The frictional resistance in the wheels and pulley is 1.2N. Calculate the acceleration of the cart.

Best ResponseYou've already chosen the best response.0can you draw a free body diagram as well. It might help me understand the question especially where the mass is.

Best ResponseYou've already chosen the best response.1You know, I never looked a pulleys very much. I should do so. Right now I can't solve your problem though, sorry.

Best ResponseYou've already chosen the best response.1so the force acting on the cart would be\[F_gf=m_ca\]where m_c is the mass of the cart. Acceleration follows from that quickly, but I'm basically figuring this out from looking at it, so it may be wrong.

Best ResponseYou've already chosen the best response.1\[F_gf=m_ca\to a=\frac{mgf}{m_c}=\frac{(0.5)(9.8)1.2}{1.5}\approx2.5m/s^2\]according to my calculations
