The maximum speed is 0.55 m/s
Explanation:
For an object in uniform circular motion, the force of friction between the object and the ground provides the centripetal force required to keep the body in motion. Therefore we can write:
where the term on the left is the frictional force and the term on the right is the centripetal force, and where
is the coefficient of static friction
m is the mass of the body
g is the gravitational acceleration
v is the speed of the body
r is the radius of the circular path
In this problem, we have:
r = 0.102 m
Substituting and re-arranging, we find the maximum speed v at which the salt shaker can rotate:

Answer:
Explanation:
Given
Time taken to reach ground is
Malda initial velocity
Let h be the height of Cliff
using
where, u=initial velocity
t=time
In first case chirpy drop downward thus u=0
For Milada there is horizontal velocity u=95 cm/s=0.95 m/s[/tex]
time taken to reach the ground will be same so distance traveled in this time with 0.95 m/s horizontal velocity is given by
Incomplete question. However, I provided a brief about Kinetic energy generation.
<u>Explanation:</u>
Interestingly, Kinetic energy in simple terms refers to the energy possessed by a body in motion.
It is often calculated using the formula E =
A good example of creating even more kinetic energy is a hand crank toy car that moves after you wind it a little, when the car moves it is generating another measure of K.E.
