A 10.0-kilogram block rests motionless on a horizontal, frictionless table. How much work must be done to accelerate the block to a speed of
5.00 meters per second?

125 J

Explanation:

Given

Mass of block

Initial velocity

Final velocity

According to the work-energy theorem, work done by all the forces is equal to the change in kinetic energy.

As the block is on the horizontal surface so, the work done by gravity is zero.

Work(W)=change in kinetic Energy

we need some answer choices, or something like that

explanation:

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
