How fast is a 90kg man running if his kinetic energy is 720 J?
zheka24 [161]
Answer:
4 m/s
Explanation:
KE=1/2mv^2
720=1/2(90)
720=45v^2
divide by 45
16= v^2
over the square root
4=v
v= 4m/s

An engine does 10 J of work and exhausts 25 J of waste heat during each cycle.
noname [10]
The thermal efficiency is defined as follows

\eta = 1 - \frac{Q_{\text{out}}}{Q_\text{in}},

and the energy which is put into the system is

Q_{\text{in}} = W_\text{out} + Q_\text{out}.

In your case Q_\text{in} = 25 \text{ J},W_\text{out}=10 \text{ J}.

So Q_\text{out}=10 \text{ J} which gives an efficiency of

\eta = 1 - \frac{10 \text{ J}}{25 \text { J}} = 0.6 = 60 \%.

On a cosmic calendar, in which the history of the universe is compressed into one year, how long is the average human life span?
netineya [11]

Answer:

If one were to use 5 billion years as the age of the universe and 75 years as the average human life span then

T = 75 / 5 E9 = 1.5E-8

The number of seconds in a year is 3600 * 24 * 365 = 3.2E7

If t = N * T   seconds in a year * fraction of human life span

t = 1.5E-8 * 3.2E7 = .48

A human life span is about 1/2 second compared to the life of the universe if the universe were compressed to a single year
