Ⓒ Macmillan Learning Two skydivers are holding on to each other while falling straight down at a common terminal speed of 54.70 m/s. Suddenly, they push away from each other. Immediately after separation, the first skydiver, who has a mass m₁ of 94.80 kg, has a velocity U₁ with the following components ("straight down" corresponds to the positive z-axis). V1.x = 4.930 m/s V1.y = 3.750 m/s V1,z = 54.70 m/s What are the x- and y-components of the velocity U₂ of the second skydiver, whose mass m₂ is 52.20 kg, immediately after separation? Assume that there are no horizontal forces of air resistance acting on the skydivers. U2,x = m/s What is the change in kinetic energy of the system AK system? AK system = joules U2,y = m/s
Item 19 If a car stops suddenly, you feel "thrown forward." We'd like to understand what happens to the passengers as a car stops. Imagine yourself sitting on a very slippery bench inside a car.

Use the following constants if necessary. Coulomb constant, k = 8.987 × 10º N · m² /C². Vacuum permitivity, €o = 8.854 × 10-12 F/m. Magnitude of the charge of the electron, e = -1.60217662 × 10–19 C. Mass of the electron, me = 9.10938356 x 10–31 kg. Unless specified otherwise, each symbol carries their usual meaning. For example, µC means micro coulomb . +Y (8, –7), q2 = -48 µC at p2 = (-8, 11) and q3 = 21 µC at Coordinates of three charges in a 2D plane is given as follows: q1 = 39 µC at p1 P3 = (-14,9). These coordinates are given in centimeters.
