A11 g plastic ball is moving to the left at 29 m/s. how much work must be done on the ball to cause it to move to the right at 29 m/s ? express your answer using two significant figures.

4.25 J

Explanation:

Given that

mass of plastic ball = 11 g

Mass of plastic ball = 0.011 kg

velocity of ball = 29 m/s

We know that from work power energy theorem

We know that kinetic energy of moving mass given as

Now by pitting the values

KE= 4.25 J

So the work done on the ball is 4.25 J

568.98
