Given that,
Distance, s= 2.4x 10∧5
Time = 6 hours
Average velocity = ?
Since,
Velocity = Distance / Time
V= 2.4 x 10∧5/ 6 = 40000 km/hr
Velocity will be 40,000 km/hr.
Convert it into m/s.
Velocity = (40,000 * 1000) / (60*60) = 11111.11 m/s
Velocity will be 11,111 m/s approx.
Newton's Second Law.
We have the following data, provided in the exercise:
Mass (m) = ?
Force (F) = 13607 N
Acceleration (a) = 2.9 m/s²
<em>To</em> calculate the mass, <em>we solve the</em> following formula:
We substitute the data in the clear formula.
<em>We break down the units of</em> Newton = Kg * m/s².
<h2>The mass of the truck is: 4692.07 Kilograms (Kg).</h2>
Answer:
10seconds
Explanation:
use the formula a=v final_v inital/time
<u>2352 Joules</u> is the “Gravitational potential energy” that a skater has.
<u>Explanation</u>:
"Gravitational potential energy" of an object is defined as the energy stored in the object which is at a height. Everybody at a height has some energy that is calculated by using the potential energy formula. Mathematically, "Gravitational potential energy" (GPE) is mass (m) times acceleration due to gravity (g) times height (h) of an object. Therefore, GPE = m × g × h.
From the given question,
Mass of the skater is 60 kg
The height at which skater is located is 4 m
“g” is acceleration due to gravity 9.8
Substitute the given values in the GPE = m × g × h
Gravitational potential energy = 60 × 9.8 × 4
Gravitational potential energy = 2352 J

Масса (килограмм), длина (метр) и время (секунда) - это 3 из 7 основных единиц в системе СИ.
Базовые единицы произвольно определены как то, что они есть, поэтому они не могут быть получены.
Все другие единицы в системе СИ являются производными от 7 основных единиц, таких как скорость (метр / секунда).
Остальные 4 - это температура (Кельвин), количество вещества (моль), электрический ток (ампер) и светимость (кандела).
