**1. If a cart is being pulled from rest by over 75cm in 2s by a suspended mass of 100g attached to the cart via a rope and pulley, what is the friction of the surface?**

**2. My question is whether the fapp force is the suspended mass. I know I need**

Ff= μFN, Fn= -(fappy+Fg) and to get acceleration I'll need d=vit+0.5at^2, is this correct so far? and is the suspended mass indeed the fapp?
