Correct answer choice is :
A) Toward the center of a circle, which changes the direction of motion but not the speed.
Explanation:
A centripetal force is a force that gives a body support a curved way. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instant center of the curve of the path. The direction of the net energy is in the same direction as the acceleration. So for an object traveling in a circle, there must be an internal force acting upon it in order to create its internal acceleration. This is seldom related to as the centripetal force demand.
Answer:
Gravitation
Explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

- <em><u>Financial planning is the process of determining the objectives; policies, procedures, program and budgets to deal with the financial activities of an enterprise.</u></em>
- Financial planning is an important part of financial planning. It reflects the needs of the business and is integrated with the overall business planning.
- it involves taking certain important decisions so that finances are continuously available to the company and are used efficiently.
(a) 3675 N
Assuming that the acceleration of the rocket is in the horizontal direction, we can use Newton's second law to solve this part:
where
is the horizontal component of the force
m is the mass of the passenger
is the horizontal component of the acceleration
Here we have
m = 75.0 kg
Substituting,
(b) 3748 N, 11.3 degrees above horizontal
In this part, we also have to take into account the forces acting along the vertical direction. In fact, the seat exerts a reaction force (R) which is equal in magnitude and opposite in direction to the weight of the passenger:
where we used
as acceleration of gravity.
So, this is the vertical component of the force exerted by the seat on the passenger:
and therefore the magnitude of the net force is
And the direction is given by
