A 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. what is its potential energy (PE) when it is 2.00 m above the grou

zloy xaker [14]

Answer:

1.5288 J

Explanation:

We can use the Energy conversion law

Energy can not be made or destroyed. It can only be converted to another form of energy

Potential Energy (PE) is the energy an object has due to its height of the location

<em>PE = mass * gravitational acceleration * height from the ground</em>

Simply here , lemming had a PE and KE also.

(g = 9.8 m/s²)

PE = 0.0780 * 9.8 *2

= 1.5288 J

A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.

Svetllana [295]

Answer:

100 Nm and 25Nm/s.

Explanation:

<u>Given the following data;</u>

Force = 25N

Distance = 4m

Time = 5secs

To find the workdone;

Workdone = force * distance

Substituting into the equation, we have;

Workdone = 25*4

Workdone = 100 Nm

To find the power consumed;

Power = workdone/time

Substituting into the equation, we have;

Power = 100/4

Power = 25Nm/s

The work done on the box is 100 Nm, and the power is 25 Nm/s.

Two spaceships are observed from earth to be approaching each other along a straight line. Ship A moves at 0.40c relative to the

nirvana33 [79]

Answer:

0.80 c

Explanation:

The computation of speed is shown below:-

Here, The speed of the captain ship A report for speed of the ship B which is

$S = \frac{S_A + S_B}{1 + \frac{(S_AS_B)}{c^2} }$

where

$S_A$ indicates the speed of the ship A

$S_B$ indicates the speed of the ship B

and

C indicates the velocity of life

now we will Substitute 0.40c for A and 0.60 for B in the equation which is

$S = \frac{0.40c + 0.60c}{1 + \frac{(0.40c)(0.60c)}{c^2} }$

after solving the above equation we will get

0.80 c

So, The correct answer is 0.80c
