The position of a ship traveling due east along a straight line is s(t) = 12t2 + 6. in this example, time t is measured in hours and position s is measured in nautical miles. we will take s = 0 to be the port of wilmington, nc and the positive direction to be east. how far east of wilmington is the ship and how fast is it going after one hour, that is, when t = 1?

By what primary heat transfer mechanism does the sun warm the earth?

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.

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
