A student who weighs 500 newtons climbed the stairs from the first floor to the third floor,15 meters above, in 20 seconds. How much work did she do

Answers

Well, the 20 seconds gives us enough information to actually calculate the power she has on her feet :)
Well, the work is 500*15=7500J, that is 7.5 kJ or about 18 calories (1 cal is 418J?) The power is that 7.5 kJ divided by 20 seconds: 375W. That's... OK, I suppose...

Answer:

Work = (500N)(15m)=7500J Power= (7500J)/(20s) =375 W

Hopefully this helps

Explanation:

A child lifts a 5.0-newton toy to a height of 0.50 meters. How much work is done on the toy?

Answers

you can use the formula

Work = force x distance

therefore, 

W= (5.0)(.50)
W = 2.5 joules

hope this helps :)
Work done=mgh
W=force*height
W=5N*0.50mts
W=2.5joule

A tiger runs one kilometer. The tiger does 15,000 J of work and has a total power output of 500 W. How many minutes does it take the tiger to run the distance? (Points : 3)0.30 sec
30 sec
3.0 sec
300 sec

Answers

Power is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. The formula would be as follows:

P = W/t 

We calculate as follows:

500 W = 15000 J / t
t = 30 s

A bicycle and rider travel along a road. Which is true?A. The bicycle and the rider undergo translation.
B. Only the rider undergoes a translation.
C. Only the bicycle undergoes translation.
D. Neither the bicycle nor the rider undergoes a translation.

Answers

Answer:

A. The bicycle and the rider undergo translation.

Explanation:

When a rider is riding his bicycle along the road, the wheels of the bicycle will rotate. This rotation of wheels translates both the rider and the bicycle in space.

So the correct answer is option A
A bicycle and rideer travel along a road. the true about the sentence is: a. the bicycle and the rider undergo translation. The rider moving because you have to push the pedals and make the bike moves too.
