A sled is at rest at the top of a slope 2 m high. The sled has a mass of 45 kg. What is the sled's potential energy?

kap26 [50]

Answer:

PE = 882 J

Explanation:

Through the International System we know that the gravity of the earth is 9.8 m/s², so...

Data:

m = 45 kg
g = 9.8 m/s²
h = 2 m
PE = ?

Formula:

$\boxed{\bold{PE=m*g*h}}$

Replace and solve:

$\boxed{\bold{PE=45\ kg*\ 9.8\frac{m}{s^{2}}*2\ m}}$

$\boxed{\boxed{\bold{PE=882\ J}}}$

The potential energy of the sled is <u>882 Joules</u>.

Greetings.

Is the series equivalent resistor larger than either resistor, or is it smaller?

VikaD [51]

The equivalent of several resistors in series is always more than the biggest single one, because it's their sum. ... In parallel, the equivalent is always less than the smallest one.
