Answer:
The elastic potential energy PE=143.47kJ
Explanation:
This problem bothers on the potential energy stored in a material.
Given data
Mass of the bungee jumper
m= 75kg
Height of jump down the cliff h=195m
We know that the elastic potential energy stored is same as the potential energy of the bungee jumper
PE= 1/2kx²= mgh
Assuming g is 9.81m/s²
PE= 75*9.81*195
PE= 143471.25J
PE=143.47kJ
What is potential energy?
Potential energy is the energy possessed by a body by virtue of it position.
Answer:
6.52m/s
Explanation:
Hello!
To solve this problem follow the steps below, the complete procedure is in the attached image
1. draw a complete outline of the problem involving forces and geometries
2. Find the time that elapses from when the ball is thrown until it hits the water, this is achieved using the kinematic equation for constant acceleration and zero vertical initial velocity.
3. taking into account that the ball is launched horizontally, and that there is no horizontal acceleration, the only thing we must do is find the speed by dividing the distance traveled horizontally and dividing it by time

<span>The correct option is: (A) 41 °F (5°C)
Explanation:
As the temperature increases (from 6-7 °C), the tendency of a bacteria to grow also increases. Therefore, it is recommended to keep the temperature of refrigeration units, salad bars and other cold items at 41 °F (5 °C) or colder. Hence, the correct answer is option (A).</span>
