**1. A lab was performed where students roller an initially stationary cart down a ramp 1.84m long. It took 1.15s to roll off the end of the ramp. What is the final velocity of the cart?**

vi=0m/s, D=1.84m, t=1.15s vf=?

vi=0m/s, D=1.84m, t=1.15s vf=?

**2. Vav=d/t, Vav= (vi+vf)/2**

**3. Vav= 1.84m/1.15s=1.6m/s 2Vav-vi=vf, 2(1.6m/s)-0=vf, therefore vf= 3.2m/s**

Sorry for wasting everyone's time with this novice problem, however, if this was firstly correct, and secondly the easiest way of finding final velocity. My textbook states a different answer and I was wondering if I made an error or if it was mistaken. Thanks.
