Current Attempt in Progress
A carnival merry-go-round rotates about a vertical axis at a constant rate. A man standing on the edge has a constant speed of
3.39 m/s and a centripetal acceleration of magnitude 2.13 m/s2. Position vector locates him relative to the rotation axis. (a) What is
the magnitude of 7? What is the direction of 7 when a is directed (b) due east and (c) due south?

Heterogeneous mixture with larger particles that never settle is

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.

Formulating a hypothesis: part i since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of " because when writing your hypothesis
