A horse does 910 J of work in 380 seconds while pulling a wagon. What is the power output of the horse? Round your answer to two
frutty [35]

Answer: 2.4 watts

Explanation:

Work done by horse = 910J

Time = 380 seconds

Power output of the horse = ?

Recall that power is the rate of doing work. Thus, power is workdone divided by time taken.

i.e Power = (work/time)

Power = 910J/380seconds

Power = 2.395 watts (rounded to two significant figures as 2.4 watts)

Thus, the power output of the horse is 2.4 watts

Answer:

Horizontal distance is 1.28 + 2.04 = 3.32 m

Explanation:

Given data:

from  below figure

Applying Pythagoras theorem

from Snell's law

\frac{sin i}{sin r} = \frac{n_2}{n_1} = \frac{\frac{EF}{AB}}{\frac{DE}{BD}}

1.33 =\frac{ \frac{2.04}{\sqrt{(3.5 -1.8)^2 + 2.04^2}}}{\frac{x}{\sqrt{1.8^2 + x^2}}}

solving for x we have

x^2 = 1.626

x = 1.28

Horizontal distance is 1.28 + 2.04 = 3.32 m
