"An object is rolled up an incline. If the object is 2.75 m up the incline after 4.50s and rolling back down at a velocity of 1.90 m/s, what is the acceleration of the object?"

Question

"An object is rolled up an incline.  If the object is 2.75 m up the incline after 4.50s and rolling back down at a velocity of 1.90 m/s, what is the acceleration of the object?"

Is this a case of final velocity - initial velocity??  It seems like an easy problem, but I don't know how to solve it.  Thanks!

CL · Answer

acceleration and velocity are two different things. try using.. d = vt + (1/2)a(t^2)

remember: the object is rolling down for this equation
