James has more power than Andy
Explanation:
Power is defined as the amount of work done per unit time:
[tex]P=\frac{W}{t}[/tex]
where
W is the work done
t is the amount of time taken to do the work
In this problem, both James and Andy do the same amount of work,
W = 50 J
However, James takes less time to do the work, so we can write
[tex]t_J < t_A[/tex]
where [tex]t_J[/tex] is the time taken by James and [tex]t_A[/tex] the amount of time taken by Andy.
Therefore, the power used by each is
[tex]P_J = \frac{50 J}{t_J}\\P_A = \frac{50 J}{t_A}[/tex]
And since [tex]t_J < t_A[/tex], this implies that
[tex]P_J>P_A[/tex]
So, James has more power than Andy.
