<h2>Answer :</h2>
□ The Final velocity of body = 45 m/s
<h2>Given :</h2>
Initial velocity of body = 0 m/s
Acceleration of body = 3 m/s²
Time taken by body = 15 sec
<h2>To Calculate :</h2>
Final velocity of body = ?
<h2>How To Calculate ?</h2>
<h3>❒ </h3>
Here in this question we are provided that a body is in rest so it's initial velocity will be 0 m/s (because from rest), Acceleration of body is 3 m/s², and Time taken is also given which is 15 sec.
<h3>❒</h3>
To calculate the Final velocity of body we'll use the first equation of motion which says v = u + at
Where,
- v is the Final velocity in m/s.
- u is the Initial velocity in m/s.
- a is the Acceleration in m/s².
- t is the Time taken in second.
<h2>Calculation :</h2>
From first equation of motion
Hence, the Final velocity of body is 45 m/s.
Answer:
Yes, they will also have the same acceleration. Acceleration is controlled by the amount of weight (def. amount of gravitational pull on a given object) that the ball has. For one ball to accelerate quicker than the other, it would need a propulsion element, which it does not.
Explanation:
Answer:
i dont really understand but when you accelerate you move faster. So i guess the skateboarder is moving fast forward
The new absloute temperature should be 4t.
<h3>Temperature </h3>
The hotness of matter or radiation is expressed by the physical quantity known as temperature.
There are three different types of temperature scales: those, like the SI scale, that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron in a body; those that solely depend on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are not defined by theoretical principles but rather by useful empirical properties of particula.
Using a thermometer, one can gauge temperature. It is calibrated using different temperature scales, each of which historically defined itself using a different set of reference points and thermometric materials.
