The shadow that will be protected on the ground will represent the hawk's horizontal position. therefore it will move at the hawk's horizontal velocity component, which is:
5*cos(60) = 2.5 m/s
Answer:
The speed of sound is 366.67 m/s.
Explanation:
height, h = 44 m
total time, T = 3.12 s
Let the time taken by the stone to hit the water is t.
use second equation of motion
Time taken by sound to g up
t'=T - t = 3.12- 3 = 0.12 s
The speed of sound is
Answer:
Explanation:
The situation can be described by the Principle of Energy Conservation and the Work-Energy Theorem:
The work done on the ball due to drag is:
Conduct an electrical charge and is measured in ohms
