Answer:
1440 W
Explanation:
First of all, we can find the total displacement of the sled, which is given by
where
a = 0.08 m/s^2 is the acceleration
t = 1 min = 60 s is the time
Substituting,
Now we can find the wotk done on the sled, equal to the product between force and displacement:
And finally we can fidn the average power, which is the ratio between the work done and the time taken:
Answer:
Image result for If the world was not tilted, what would happen to the people living on Earth
If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant
Explanation: i looked up the answer
This one is easy. You just find the rise over run for the graph. Here, its 3/2 m/s.
The description of the problem is a bit ambiguous as "<span>increasing at the rate of </span>3 inches more than the time" can be interpreted in many ways. Assuming the increase rate is the (3+t) per second and as it expands for 3 seconds, then the diameter of the sphere would be:
d= (3 + t)*t
d= 3t + t^2= 18
r= 1/2 d
r= 1/2*18= 9
volume= 4/3 * pi * r^3
volume= 4/3 * pi * 9^3
volume= 4/3 * pi * 729= 972 pi cubic inches
