Question 1 While curling, you push a rock for 2.00 m and release it when it has a speed of 1.90 m/s. It continues to slide at constant speed for 0.600 s and then hits a rough patch of ice. It finally comes to rest 9.60 m from where it was released. What was the curling rock's magnitude of acceleration after it hit the patch of rough ice? Question 2 Mary is standing at the top of a hill admiring the view. The hill is at a 3.10' tilt. 24.0 m down the hill an old man lets go of a stroller with a baby inside it. The stroller starts to roll downhill with its frictionless wheels. Mary starts to run after it with her best acceleration of 2.40 m/s. How far has the stroller rolled before she catches it
