Answer:
It have 1.359 joule kinetic energy.
Explanation:
- Kinetic energy is defined as the energy of any object due to its state of motion.
- Mathematically kinetic energy can be calculated as:
K.E = 
...........................equation 1
where,
m= mass of object
v= velocity of that moving object
mass= 2500 lbs = 
kg.
velocity= 80mph= 
= 
.
- Substituting the values in equation 1, we get;
K.E= * * 
K.E= 
Answer:
The height of the squirrel 
Explanation:
From the question we are told that
The horizontally speed is 
The horizontal distance 
Generally the the time taken is mathematically represented
=> 
=> 
Generally from kinematic equation we have that
Here u is the initial velocity of nut in the vertical and the value is 0 m/s
=>
<u>Answer:
</u>
C option is correct
20 movable and 20 fixed pulleys required
<u>Explanation:
</u>
To lift a 27,800 N elephant with a 700 N drive,
27800/700=39.7
the individual requires a mechanical favorable position of 39.7 which is equivalent to 40. A solitary movable pulley gives a mechanical favorable position of 2, two portable pulleys yield a mechanical preferred standpoint of 4, and a framework with three movable pulleys results in a mechanical favorable position of 6. In light of this example, 20 movable pulleys and 20 fixed are required to give a mechanical preferred standpoint of 40
The answer would be Nicholas Coperniucus
Answer:
<h2> B. Components</h2>
Explanation:
Splitting vectors into components makes it easier to perform operations on them, typically categorizing vectors into horizontal and vertical components which are the two components makes it very easy to perform operations, since they are similar terms and operations cab be done easily
