Answer:
The force will be
Explanation:
Let's use the centripetal force equation.
Where:
m is the mass of the bunch of bananas
ω is the angular speed
R is the radius
Now, 1 rev every 4 seconds or 0.25 rev/sec is the angular speed, but we need to write this speed in rad per second.
FInally, the force will be:

Answer:
t=62 s
Explanation:
Applying the conservation of linear momentum formula:
the initial velocity is zero, we can calculate the man's mass using the gravitational force formula:
now:
That is 0.13m/s due south.
because there is no friction, the man will maintain a constant velocity, so:
Answer:
atm
Explanation:
The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column
Thus,
Substituting the given values, we get -
kg/m3
m/s^2
meters
atm
