While hammering a nail, you put in 30 Joules of work. The hammer then puts out 10 J of
AfilCa [17]

Answer:

C    Don't worry if you thought it was D. I almost answered that.

Explanation:

Remark

You can get this just by learning the vocabulary.

Efficiency = Work Out / Work In * 100%

Work in = 30J      That's you swinging the hammer.

Work out = 10 J    That's how much of the hammer's work gets to the nail.

Efficiency = (10/30)*100

Efficiency = 1/3 * 100

Efficiency = 33%

A 35 kg object has -450 kgm/s of momentum. Calculate its velocity.
shtirl [24]

Hi there!

Recall the equation for momentum:

\large\boxed{p = mv}\\

p = momentum (kgm/s)

m = mass (kg)

v = velocity (m/s)

We can plug in the given values to solve for velocity:

-450 = 35v\\\\v = \frac{-450}{35} = \boxed{12.86 m/s}
