#### Explanation:

kinetic energy is

The mass is 1.45 g

The velocity is 13.5 cm/s

putting these values in for mass and velocity yields

It is possible the instructor wants the units changed to meters/s and kilograms

#### Explanation:

Remember that the SI unit for mass is kilograms and the SI unit for velocity is metres per second.
