A person , sunbathing on a warm day, is lying horizontally on the deck of a boat. Her mass is 59 kg, and the coefficient of static friction between the deck and her is 0.70. Assume that the person is moving horizontally, and that the static frictional force is the only force acting on her in this direction .
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
A person , sunbathing on a warm day, is lying horizontally on
the deck of a boat. Her mass is 59 kg, and the coefficient of static
friction between the deck and her is 0.70. Assume that the person is
moving horizontally, and that the static frictional force is the only
force acting on her in this direction .
(a) What is the magnitude of the static frictional force when the boat moves with a constant velocity of +8.0 m/s?
(b) The boat speeds up with an acceleration of 1.6 m/s2 and she does not slip with respect to the deck . What is the magnitude of the static frictional force that acts on her?
(c) What is the magnitude of the maximum acceleration the boat can have before she begins to slip relative to the deck ?
