Answer:
[tex]\boxed {\boxed {\sf 750 \ J}}[/tex]
Explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated using the following formula.
[tex]E_k= \frac{1}{2} mv^2[/tex]
In this formula, m is the mass and v is the velocity.
The bicycle has a mass of 15 kilograms and a velocity of 10 meters per second.
Substitute the values into the formula.
[tex]E_k= \frac {1}{2} (15 \ kg)(10 \ m/s)^2[/tex]
Solve the exponent.
- (10 m/s)²= 10 m/s * 10 m/s = 100 m²/s²
[tex]E_k= \frac{1}{2} (15 \ kg)( 100 \ m^2/s^2)[/tex]
Multiply all the values together.
[tex]E_k= \frac{1}{2} ( 1500 \ kg*m^2/s^2)[/tex]
[tex]E_k= 750 \ kg*m^2/s^2[/tex]
1 kilogram meter squared per second squared is equal to 1 Joule. Therefore, our answer of 750 kg*m²/s² is equal to 750 J.
[tex]E_k= { 750 \ J[/tex]
The kinetic energy of the bicycle is 750 Joules.
