An object of mass 11 kg is released at point A, slides to the bottom of the 30° incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. The spring constant is 550 N/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. A 2.0 m 30° Image Description a. What is the speed of the object at the bottom of the incline? V = 5.3 o m/s Correct! b. What is the work of friction on the object while it is on the incline? W; = J * Is the sign correct? c. The spring recoils and sends the object back toward the incline. What is the speed of the object when it reaches the base of the incline? U = 5.30 o m/s Correct! d. What vertical distance does it move back up the incline? h = m Incorrect.
