Hint 1 Hint 2 An object of mass 9.5 kg is released at point A, slides to the bottom of the 3D\" incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. The spring constant is 4?5 Him, the height of the incline is 2.0 m, and the horizontal surface is frictionless. A 2.0 m l an. Image Description I a. What is the speed of the object at the bottom of the incline? h. What-is the work of friction on the ohject while it is on the incline? WI: .1525 J I! Correct! c. The spring reooiis anci sends the object back toward the incline. What is the speed of the object when it reaches the base of the incline? V Correct! cl. What vertical distance does it move back up the incline? h = 2.869 X m I * Incorrect
