Answer:
6,653.34 J
Explanation:
Kinetic energy can be found using the following formula.
[tex]KE=\frac{1}{2} mv^2[/tex]
where m is the mass in kilograms and v is the velocity in m/s.
The object is 108 kilograms and is moving at a speed of 11.1 m/s. Therefore, the mass is 108 kg and the velocity is 11.1 m/s.
m=108 kg
v=11.1 m/s
Substitute these values into the formula.
[tex]KE=\frac{1}{2}*108*11.1^2[/tex]
Evaluate the exponent first. 11.1^2 is the same as 11.1*1.11, which is equal to 123.21
[tex]KE=\frac{1}{2} *108*123.21[/tex]
Multiply 108 and 123.21
[tex]KE=\frac{1}{2}*13306.68[/tex]
Multiply 1/2 and 13306.68
[tex]KE=6653.34[/tex]
The kinetic energy of the object is 6,653.34 Joules (kg m2/s^2)
