A block of mass m slides down from rest on a rough incline of length 8m where the incline makes an angle of 30° with the horizontal. The block comes to rest on the rough horizontal surface after sliding for 4 m. The coefficient of kinetic friction on the incline is 0.30. The coefficient of kinetic friction on the horizontal surface is different from the incline, find this value using two approaches: (i) Using Newton's laws of motion and Kinematics and 30⁰ (ii) Using Work-Kinetic Energy Theorem (Give answer to 2 sig. figs.) 4 m 8 m WA

Redo Example 5, assuming that there is no upward lift on the plane generated by its wings. Without such lift, the guideline slopes downward due to the weight of the plane. For purposes of significant figures, use 2.91 kg for the mass of the plane, 12.2 m for the length of the guideline, and 18.2 and 36.4 m/s for the speeds. (a) Number (b) Number Units Units
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 1.67 s. The mass of the book bag is 3.60 kg, the length of the slide is 3.70 m and the angle of incline is 28.0°. (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? m/s2 (b) What is the friction force (in N) acting on the bag? (e) What is the coefficient of kinetic friction between the bag and the slide? (d) What is the speed (in m/s) of the bag when it reaches the bottom of the slide? m/s
A bicyclist can coast down a 6.17 degree hill at a constant speed of 6.64 km/h. If the force of air resistance is proportional to the speed vso that Fair = c v, calculate the average force (in N) that must be applied in order to descend the hill at 13.0 km/h. The mass of the cyclist plus bicycle is 77.8 kg.
