Answer: set up proportions
Explanation:
Energy stored= Li^2/2
Therefore L=2(E.S)/i^2
= 0.0013
Answer:
I would say a pond
Explanation:
A pond is more still than an ocean, therefore you could see your reflection better
Answer: The acceleration of the object is 0.67m/s^2 west.
Explanation: Here we are given the initial velocity and final velocity as well as the time taken. Acceleration is the change in velocity per unit time, thus the equation becomes.
a=dv/t
a=vf-vi/t
a=-2.1-4.7/3.9
a= 0.66m/s^2 west
Answer:
Explanation:
The velocity of the swimmer just before touching the water is:
The average force exerted on the diver by the water is determined by the use of the Principle of Energy Conservation and the Work-Energy Theorem:
