What is the relationship between kinetic and potential energy of a falling object

Physics
1 answer:
borishaifa [10]3 years ago
5 0

Answer:

See the explanation below.

Explanation:

According to the law of energy conservation. This can be transformed from potential energy to kinetic or vice versa.

For example, when you have a body at rest at a height with respect to the ground level, this body possesses potential energy with respect to the ground, but the moment that the body falls the potential energy decreases as it loses height with respect to the ground, but as the potential energy decreases, the kinetic energy increases, that is to say, the potential energy is transformed into kinetic energy as the body is falling.

As the energy relationship is maintained we can say that the potential and kinetic energies are equal.

E_{pot}=m*g*h\\E_{kin}=\frac{1}{2} *m*v^{2} \\E_{pot}=E_{kin}

Answer:

<h3><em>28.01m/s.</em></h3>

Explanation:

Given maximum height reached by the ball as H = 40 metres

Since the ball rises straight up when hit by a ball, then the angle of launch will be perpendicular to the ground and that is 90°.

To determine the upward speed of the ball in meters per second after it got struck by the bat, we will use the formula for calculating the maximum height according to projectile motion;

Maximum Height H = \frac{u^2sin^2\theta}{2g} where;

u is the speed of the ball

\theta is the angle of launch

g is the acceleration due to gravity = 9.81m/s²

Substituting the given parameters into the formula;

40 = \frac{u^2sin^2(90)}{2(9.81)}\\ \\40 = \frac{u^2}{2(9.81)}\\ \\40 = \frac{u^2}{19.62} \\cross\ multiply\\\\u^2 = 40*19.62\\u^2 = 784.8\\u = \sqrt{784.8}\\ u = 28.01 m/s

<em>Hence the upward speed of the ball in meters per second after it got struck by the bat is 28.01m/s.</em>
