Three forces are exerted on an object placed on a slope in the figure. the forces are measured in newtons (n). 1. assuming that forces are vectors, what is the component of the net force f⃗ net=f⃗ 1+f⃗ 2+f⃗ 3 parallel to the slope? 2. what is the component of f⃗ net perpendicular to the slope? 3. what is the magnitude of f⃗ net? 4. what is the direction of f⃗ net?

The two required components for a generator are

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
