Answer:
The velocity of the skateboard is 0.774 m/s.
Explanation:
Given that,
The spring constant of the spring, k = 3086 N/m
The spring is stretched 18 cm or 0.18 m
Mass of the student, m = 100 kg
Potential energy of the spring,
To find,
The velocity of the car.
Solution,
It is a case of conservation of energy. The total energy of the system remains conserved. So,
v = 0.774 m/s
So, the velocity of the skateboard is 0.774 m/s.
Actually the
Kinetic Energy, which is also known as the energy of motion is directly
proportional to temperature. So the higher the temperature is, the faster the gas
particles move so they have possess more kinetic energy.
This temperature is in
absolute units so we convert to Kelvin:
200 C = 473.15 K
100 C = 373.15 K
So the amount increase
is:
473.15 / 373.15 =
1.268
<span>It will increase by a
factor of 1.268 or 126.8%</span>
