How long (in seconds) would it take a machine to do 13,771 joules of work if the power rating of the machine is 0.38 horsepower? (Give the answer without units and round it to the nearest whole number.)
The formula of time is energy/power So you substitute the numbers in the formula 13.771/0.38=36.24s. But it’s telling you to give it to the nearest whole number so it’s just 36s.
