Calculate change in height of a 2kg ball moving a speed of 10m/s up a frictionless ramp until it stops
Nataliya [291]

The change in the height of the object is 5.1 m.

<h3>Conservation of mechanical energy</h3>

The principle of conservation of mechanical energy states that the total energy of an isolated system is always conserved.

The change in the height of the object is calculated by applying the principle of conservation of mechanical energy as follows;

P.E = K.E

mg \Delta h = \frac{1}{2} mv^2\\\\g \Delta h = \frac{1}{2}v^2\\\\\Delta h = \frac{v^2}{2g} \\\\\Delta h = \frac{(10)^2}{2(9.8)} \\\\\Delta h = 5.1 \ m

Thus, the change in the height of the object is 5.1 m.

trapecia [35]

Answer:

- Problem-recognition.

Explanation:

The consumer decision-making process is associated with the process of consumers recognizing their needs and requirements, collecting information followed by the evaluation of distinct alternatives available in the market and then finally reaching a decision to opt for a specific product to buy.

As per the given description, Gilbert's evaluation of his need that his current phone is not able to meet up his requirement and realization that he requires a phone with a longer-battery life exemplifies that he is in the '<u>problem-recognition</u>' phase of the consumer decision-making process. This stage would be followed by the assessment of alternatives(various phones with longer battery life) and reaching the conclusion to buy a specific chosen product after the evaluation.
