Question

A child uses 3.5N to throw a ball into the air about 2.3 meters, how much work has she achieved?

a.)1.2 J
b.)5.8 J
c.)8.05 J
d.)1.521 J

Answer 1

The child has achieved 8.05 joules of work by throwing the ball into the air. The correct answer is option c) 8.05 J.

Step-by-step explanation:

The question asks how much work a child has done by throwing a ball into the air. To calculate work, we use the formula Work = Force × Distance. In this scenario, the child uses a force of 3.5 N to throw the ball 2.3 meters high.

To calculate the work done by the child in throwing the ball into the air, we can use the formula:

Work = Force × Distance

Given that the force exerted by the child is 3.5N and the distance the ball is thrown is 2.3 meters, we can substitute these values into the formula:

Work = 3.5N × 2.3m

Work = 8.05 J

Therefore, the child has achieved 8.05 joules of work. The correct answer is option c) 8.05 J.
