The magnitude of the acceleration of the runner is given by:
where
is the final speed of the runner
is the initial speed of the runner
is the time taken
By substituting data into the equation, we find the magnitude of the acceleration:
1/2 M V² ==(1/2) (5) (16) = 40 J
i think that may be correct ☺
I believe the answer would be, refractor type telescopes because these are best used for planetary observations.
Answer: ultraviolet
explanation: The highest frequency is ultraviolet, because it can cause skin cancer, and many more things
Answer:
95.5ms-2
Explanation:
First we obtain the time taken for the motion from the equation of motion. Secondly we obtain the horizontal velocity of the stone. This can now be used to calculate the centripetal acceleration. Note that the length of the chord is the radius of the circle around which the stone moves.
