Answer: 14.28 m/s
Explanation:
Assuming the girl is spinning with <u>uniform circular motion</u>, her centripetal acceleration is given by the following equation:
(1)
Where:
is the <u>centripetal acceleration</u>
is the<u> tangential speed</u>
is the <u>radius</u> of the circle
Isolating from (1):
(2)
<u />
Finally:
This is the girl's tangential speed
Answer
given,
mass of the stick = 290 grams = 0.29 Kg
Force on the stick on one side = F = 9 N
force acting perpendicular to stick.
magnitude of acceleration
rate of change of angular momentum is equal to Force
rate of change of angular momentum = 9 N
F = m a
a = 31.034 m/s²
Direction of motion will in the direction of force application or in the direction of change of velocity
-6.7cm just took the time to put this answer down because its been helping me and its right so good luck
Explanation:
Mechanical energy (the sum of potential and kinetic energy) is constant:
ME = PE + KE
ME = PE + ½ mv²
PE = ME − ½ mv²
So the slope of the line is -½ of the mass.
Steel is more dense because it’s heavy while water is light
