# Is Vx accelerating? (simple yes/no question)

on earth, there is this object pushed off of a cliff. I know it is accelerating on the y axis, but is the object accelerating in the x axis?

i have the distance from Xo to Xf (.35m) as well as the time it takes to get there (.349927s)

Force= mass * acceleration. Is there any force in the x-direction?

Are there any forces in the x direction (after it's pushed)?

EDIT: Such timing!

someone pushes it 1.6 meters before it reaches the cliff, where it decelerates as a result of friction and falls off the cliff

I'm guessing this problem is supposed to start after the fall, so you probably don't have to consider forces that acted prior to that. After the fall, are there any forces in the x direction?

no, so i guess its not accelerating. thanks so much

No, it is not acceleratiing in the X direction. Acceleration is only at beggining.
anyway..cya
