It shows that acceleration of particle M is directly proportional to its displacement and its direction is opposite to that of displament. Thus particle M performs simple harmonic motion but M is projection of particle performing U.C.M. hence S.H.M. is projection of U.C.M. along a diameter, of circle.
Answer:
my dad is a physics professor so when he comes home i will tell him to answer the question for you
Answer:
4.0 m/s
Explanation:
In the first part of the run, the athlete runs a distance of

at a speed of

So, the time he/she takes is

In the second part of the run, the athlete covers an additional distance of

with a speed

So, the time taken in this second part is

So, the total distance covered is
d = 300 m + 300 m = 600 m
And the total time taken
t = 100 s + 50 s = 150 s
Therefore, the average speed for the entire trip is
