Answer:
0.061 J
Step-by-step explanation:
The kinetic energy of an object is given by
![K=(1)/(2)mv^2](https://img.qammunity.org/2020/formulas/physics/middle-school/c6fs3acuplloc3whu5cpc8ui63cnl7ur39.png)
where
m is the mass of the object
v is its speed
For the toy truck in the problem, we have
m = 0.1 kg is its mass
v = 1.1 m/s is its speed
Putting the numbers into the equation, we find
![K=(1)/(2)(0.1 kg)(1.1 m/s)^2=0.061 J](https://img.qammunity.org/2020/formulas/physics/middle-school/w4bzx2rt12ml31o1ijfvq9ihe7s7tsdygj.png)
