Describe what it meant by "a constant change of direction". Identify whether the examples provided show a constant change of direction when moving.(S8P3a) a. A merry-go-round spinning in circles.
b. A wind vane swinging around.
c. A person running at 5 meters/second along a curving path.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

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.

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
