A ball is thrown straight upward. At 5.90 m above its launch point, the ball’s speed is one-half its launch speed. What maximum height above its launch point does the ball attain?

Which subatomic particle has a negative charge

Which of the following is not a physical property of mattera. melting pointb.heat of combustionc. viscosityd. boiling point

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.
