Answer:
48 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.
We know the mass is 24 kilograms and the velocity is 2 m/s Therefore, substitute 24 in for m and 2 in for v.
[tex]KE=\frac{1}{2}*24*2^2[/tex]
Evaluate the exponent first. 2^2 is the same as multiply 2, 2 times.
2^2=2*2=4
[tex]KE=\frac{1}{2}*24*4[/tex]
Multiply 24 and 4
[tex]KE=\frac{1}{2} *96[/tex]
Multiply 96 and 1/2, or divide 96 by 2.
[tex]KE=48[/tex]
Add appropriate units. Kinetic energy uses Joules, or J
[tex]KE=48 Joules[/tex]
The kinetic energy is 48 Joules
