Explanation:

[tex]power = \frac{energy \: expended}{time} [/tex]

m = 7.3kg

u = 0

v = 14m/s

t = 1.5sec

P = (0.5×7.3×14²) ÷ 1.5

P = 476.93

P = 477 watt

The power is 744 watts

The first step is to write out the parameters

mass= 7.3kg

v= 14

u= 0

time= 1.5 secs

power= energy/time

= 0.5×7.3×14²/1.5

= 0.5×7.3×196÷ 1.5

= 715.4÷ 1.5

= 477

Hence the power that was developed is 477 watts
