Question

Akito pushes a wheelbarrow with 800 W of power. How much work is required to get the wheelbarrow across the yard in 12 s? Round your answer to the nearest whole number.
It takes blank J of work to get the wheelbarrow across the yard

Answer 1

800 x 12 = 9,600
9,600 is your answer

Answer 2

Answer:

9600 J

Explanation:

The power is given by the ratio between the work done and the time taken:

$P=\frac{W}{t}$

where W is the work done and t the time taken.

In this problem, we know the power:

P = 800 W

and the time taken:

t = 12 s

So, we can re-arrange the equation to get the work required:

$W=Pt=(800 W)(12 s)=9600 J$
