Example of energy transfer from potential to kinetic and back

1 answer:

5 0

Swimmer and Divers. The Potential energy is transferred into Kinetic energy, and allows the diver to submerge into the water. The Kinetic energy then allows the diver to submerge and dive into the water. Potential energy however, is needed to allow the diver to get back out of the water after diving to get up and go and dive again, and then the Kinetic energy is transferred back to Potential energy to repeat the process.

A 4 kg bowling ball moving at 1.4 m/s east impacts a 400 g pin that is stationary. After the impact, the ball is moving at 0.5 m

nignag [31]

The speed of the pin after the elastic collision is 9 m/s east.

<h3>Final speed of the pin</h3>

The final speed of the pin is calculated by applying the principle of conservation of linear momentum as follows;

m1u1 + mu2 = m1v1 + m2v2

where;

m is the mass of the objects
u is the initial speed of the objects
v is the final speed of the objects

4(1.4) + 0.4(0) = 4(0.5) + 0.4v2

5.6 = 2 + 0.4v2

5.6 - 2 = 0.4v2

3.6 = 0.4v2

v2 = 3.6/0.4

v2 = 9 m/s

Thus, The speed of the pin after the elastic collision is 9 m/s east.

Two spheres each carry a charge of 1 x 10-7 C. Their centers are separated by

padilas [110]

We have that the force between the two charged objects is mathematically given as F=2.349N

The magnitude of the force between two charged objects.

Given,

Question Parameters:

Two spheres carry a charge of 1x10^-7 C.

Their centers are separated by 0.7m.

Generally, the equation for the Force is mathematically given as

$F=^{\fra\frac{q 1 q 2} {4 * \pi e * \tau}$

Therefore

$F=^\frac{(1 e-7)^{2}}{9 e 9 * 0.7}$

F=2.349N

<h3>What is magnitude?</h3>

In mathematics, the magnitude or size of a mathematical entity is a property that determines whether the object is bigger or slighter than different things of the same kind. Additional formally, an entity's magnitude is the declared result of an ordering —of the class of things to which it belongs.
