The particle will have an energy of 12U0. A particle travels at an initial velocity from point B to point A, gaining U0 joules of kinetic energy along the way. The constant force at this point is equal to 12F.
<h3>Does 9.8 represent gravity?</h3>
The acceleration which gravity gives to objects falling freely serves as a gauge of its strength. The gravity's acceleration at Earth's surface is approximately 9.8 meters (32 feet) per second every second.
<h3>What is a good illustration of gravity?</h3>
The following are a few instances of the power of gravity: the energy holding the gases inside the sun. the power behind a ball's descent after being thrown into the air. the force that makes an automobile coast down even when the gas is not depressed.

The coefficient of kinetic friction between the baserunner and the ground is 0.51.
<h3>
Coefficient of kinetic friction </h3>
The coefficient of kinetic friction between the base runner and the ground is calculated as follows;
μ = a/g
where;
- a is acceleration
- g is gravity
v² = u² + 2as
a = (v² - u²)/(2s)
a = (8.451² - 2.322²)/(2 x 6.596)
a = 5 m/s²
μ = 5/9.8
μ = 0.51
Thus, the coefficient of kinetic friction between the baserunner and the ground is 0.51.

It has potential energy because of its position.
The tangential velocity of the car is 124.5 m/s
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by:
where
a is the acceleration
v is the tangential velocity
r is the radius of the circle
For the car in this problem, we have:
is the centripetal acceleration
r = 155 m is the radius of the turn
Solving for v, we find the tangential velocity of the car:
