Answer:
what is the question?
Explanation:
I'm not sure if this was a question because you gave the answer lol
Answer:
kinetic energy = 414 J
Explanation:
given data
mass = 23 kg
speed = 6 m/s
height = 17 m
to find out
kinetic energy
solution
we get kinetic energy that is express as
kinetic energy = 0.5 × m × v² ..........................1
here m is mass and v is speed so
put here value we get kinetic energy
kinetic energy = 0.5 × 23 × 6²
kinetic energy = 414 J
Answer:
The coefficient of kinetic friction μ = 0.278
Explanation:
The frictional force on the crate is given by F = μN where μ = the coefficient of kinetic friction and N = normal force. The normal force equals the weight of the crate W = 180 N.
Since the kinetic friction F = 50 N, and the normal force which is the weight of the crate equals N = W = 180 N, the coefficient of kinetic friction μ is given by μ = F/N
= 50 N/180 N
= 0.278
So, the coefficient of kinetic friction μ = 0.278
Answer: 1- Issac Newton is the man who discovered gravity. he is important because he found out why everyone was pulled down to the ground. this would later hepl disprove the flat earth theory.
2- Id on't know the vocab words. do those. it'll be the quickest.
3- wieght is how much is being pulled to the ground. mass is how big you are. A pound of rocks and a pound of feathers wiegh the same, but the mass of a pound of feathers will be much greather, as it takes much more feathers to equal a poud than rocks.
Explanation: CHEACK ALL SPELLING!!!! I can't spell that well and my g key doenst like working.
The distances are:
- E and F: 4 units.
- C and D: 5 units.
- G and H: 3 units.
- A and B: 6 units.
Why?
We can find the distance between each pair of points using the following formula:

So, calculating we have:
- E(-2, -1) and F(-2, -5):

- C(-4, 1) and D(1, 1):

- G(3, -5) and H(6, -5):

- A(5, 4) and B( 5, -2):

Have a nice day!
