In 10 seconds, a lion did 150 J of work moving her lion cub up a tree for safety. How much power did she use?
1 answer:
Answer:
15W is the power used by the lion to take cub up a tree.
<u>Explanation:</u>
In the given question it is said that the total work done by the lion is 150 joules and the required time is 10 seconds. According to mathematical formula of power, Power substitute the given terms in the formula =
=15 = 15W (Watt is the SI unit of power. Watt is said as one joule per second). The power used by a lion to safe her cub is 15W.

<h2>Hello!</h2>
The answer is: 19.59 m
<h2>Why?</h2>Since there is no information about the launch type, we can assume that the ball is thrown vertically upward.
When the ball reaches the maximum height, just at that moment, the velocity turns to 0, and after that moment, the ball starts falling, so:
We will use the following formula:
Where:
Vf= Final velocity = 0
Vi= Initial velocity =
g = Gravity Acceleration =
s = Traveled distance
