rotational kinetic energy of it's particles
Answer:
work done will be equal to 305.05 J
Explanation:
We have given force exerted F = 45 N
Angle with the horizontal 
Distance moved due to exerted force d = 9.1 m
Work done is equal to
, here F is force
is angle with horizontal and d is distance moved due to force
So work done 
So work done will be equal to 305.05 J
The answer is A. Only an object in motion has kinetic energy.
i’m pretty sure it’s , the alkali metals
