A child leaves her book bag on a slide. The bag, which is at the top of the slide, starts from rest and reaches the bottom in 1.63 s. The mass of the book bag is 3.85 kg, the length of the slide is 3.10 m and the angle of incline is 33.5°. (Assume the +x-axis to be parallel to and down the slide. For all values, enter the magnitude only.) (a) with what acceleration (in m/s²) does the bag go down the slide? 4.49 X Which of the kinematic equations would be appropriate for this situation? m/s² (b) What is the friction force (in N) acting on the bag? 3.54 X Did you draw a free-body diagram and identify all the forces acting on the bag? Take the x direction to be parallel to the ramp and the y direction to be perpendicular to the ramp. N (c) What is the coefficient of kinetic friction between the bag and the slide? 0.113 What is the relationship between friction force and normal force? (d) What is the speed (in m/s) of the bag when it reaches the bottom of the slide? 7.32 X Which of the kinematic equations would be appropriate for this situation? m/s
