The object has gained

#### Explanation:

The initial kinetic energy is:

#m# is the mass of the object in kilograms

#v_1# is the initial velocity, which is#5 \ "m/s"# .

And so, we get,

The final kinetic energy is:

#v_2# is the final velocity, which is#10 \ "m/s"# .

Again, we just plug in values into the equation, and we get,

The change in kinetic energy is:
