Hello!
The answer is:
Answer: 34
Units: Joules
[tex]KE=34J[/tex]
Why?
The kinetic energy is the work needed to accelerate an object to a determined speed.
The kinetic energy can be calculated using the following equation:
[tex]KE=\frac{1}{2}mv^{2}[/tex]
Where,
m, is the mass of the object.
v, is the speed of the object.
So, we are given the information:
[tex]mass=17kg\\\\v=\frac{2m}{s}[/tex]
Then, substituting and calculating we have:
[tex]KE=\frac{1}{2}mv^{2}[/tex]
[tex]KE=\frac{1}{2}*17kg*(\frac{2m}{s})^{2}[/tex]
[tex]KE=8.5kg*(\frac{4m^{2}}{s^{2}})[/tex]
[tex]KE=34\frac{kg.m^{2}}{s^{2}}=34J[/tex]
Have a nice day!
