The 1.5 kg physics book in figure is connected by a string to a 450 g coffee cup. The book is given a push up the slope and released with a speed of 3.3 m/s . The coefficients of friction are us = 0.50 and #k = 0.20. (Figure 1) Figure 1 of 1 > 200A 78.0 kg skydiver can be modeled as a rectangular "box" with dimensions 21.0 cm x 47.0 cm x 181 cm . The air drag force on a falling object can be approximated using the formula F = = . C . p . A . v . In this formula, O is the drag coefficient which in approximately 0.80 for this scenario, p is the density of air which is 1.30 kg A is the cross sectional area, and v is the speed at which the object is falling
