1. The problem statement, all variables and given/known data 1 An object is pushed up a smooth incline of 30 degrees with a speed of 4m/s. In seconds, how long will it take before the object stops and reverses direction? Vf= Vo - at Vf= Vo - at 0 = 4 - (9.8)t t = 0.41s I know this is wrong because the angle isn't accounted for, but I'm not sure where to use it. I'm not sure what the right answer is either. 2 An object is placed on an incline of 30 degrees . The object is pushed up the incline at the initial speed vo=4m/s. How far does it travel before stopping and reversing direction? Vf= Vo - at Vf= Vo - at 0 = 4 - (9.8)t t = 0.41s x= (Vxo)(t) x= (4)(0.41) x=1.6m For some reason, this gives me the right answer, but I again don't use the 30 degrees anywhere. What should I be doing?
