I would say Anthony has more power than Angel. If they are both exerting the same force on the box, which isnt really mentioned here, which is why I believe this is a bit vague, then the both do the same work. So, if the work is equal then the person with the lower time period would have more power. Since Anthony only took 38 seconds, compared to Angel's 42 I would say that Anthony has more power than Angel.

how many days does it take a team of drivers to drive a truck california and back to lansing if the drivers average 15m/s includ

malfutka [58]

4days and 12hours

Explanation:

Given parameters:

Average speed = 15m/s

Distance = 1800 miles

Unknown:

Number of days = ?

Solution:

Speed is the rate of change of distance with time;

Speed = $\frac{distance}{time}$

Since the unknown is number of days, it is a measure of time:

Time = $\frac{distance }{speed}$

The distance from California to Lansing is 1800miles. The journey takes the truck drivers to and fro. It is a two way trip;

Total distance = 1800 miles x 2 = 3600miles

We need to convert miles to meters since that is the unit we can conveniently work with;

1 mile = 1609.34m

3600 miles = 3600 x 1609.34

= 5793638m

Inputting the values in the equation:

Time = $\frac{ 5793638}{15}$ = 386242.53s

Now we need to convert to day;

In a day, = 60 x 60 x 24 = 86,400s

1 day = 86400s

Therefore;

The number of days = $\frac{386242.53}{86400}$ = 4.47days

This implies that it will take them 4 days and approximately 12 hours.

Calculate the potential energy of a 1200 kg boulder on a cliff 45 m above the ground.

Softa [21]

Explanation:

Given mass of the object is 1200kg and it's placed at a height of 45m above the ground. As we know that potential energy is ,

$\longrightarrow PE = mgh$

where,

m is the mass of the body .
g is acceleration due to gravity.
h is the height above the ground .

Substituting the respective values ,

$\longrightarrow P.E. = 1200kg * 10m/s^2* 45m$

Multiply ,

$\longrightarrow P.E. = 540000J$

<u>Hence</u><u> the</u><u> </u><u>potential</u><u> energy</u><u> is</u><u> </u><u>5</u><u>4</u><u>0</u><u>0</u><u>0</u><u>0</u><u>J</u><u> </u><u>.</u>
