Question

number 6 and 7

Use the following information for questions 1-9. From rest, a 26.7 kg child is sliding down a 5.12 meter long playground slide in a time of 1.98 seconds. The slide forms a 32.0 degree with the horizontal ground. Assume that the child stays in contact with the slide for its entire length and that there is friction between the child and slide. Complete the following table. You must include the actual, calculated values to receive credit, not the equations. If a component is 0.00 N you must indicate that, not leave it blank. Clearly and concisely explain why the sum of the forces in the y direction is 0.00 N based on the information given on the problem, not the equations given above. Calculate the child's weight W. Calculate the child's acceleration a_x along the slide. Calculate the magnitude and direction of f_k Calculate the value of mu_k
