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:
Explanation:
As we know that the total mass of the all four players is given as
diameter of the piston of cheer leader is given as
are of cross-section is given as
mass of the cheer leader is given as
m = 55 kg
so the pressure due to cheer leader is given as
Now on the other side pressure must be same
so we have
so diameter on the other side is given as
It's by..................
energy/time
Answer:
a) 17.086m
b) 0.1671 m
Explanation:
Given data: speed of water through the hose = 1.81 m/s
through the nozzle = 18.3 m/s
We know that maximum height of an object with upward velocity v is given by,
a) H = v^2/2g
where H is the maximum height water emerges
= 18.3^2/(2×9.8) = 17.086 m answer
b) Again,
H = v^2/2g
= 1.81^2/(2×9.8) = 0.1671 m
