East is our x axis
north is out y axis N

S
so he moves 3 m to the right and then 4 upwards
imagine what that looks like.......... a right angle triangle
therefore we can use Pythagorean theorem
let the unknown side be x, which is the hypotenuse in this case
x^2 = 3^2 + 4^2
x^2 = 9 + 16
x^2 = 25
take the square root
x = 5
5 is your magnitude and the direction is NE( North East) or positive direction
Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy
Spring potential energy =potential energy due to elevation
0.5*k*x²= mg
=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy
spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*
10812.88 *2.3²=430*
=11.53 m/s
<span>A rope with knots having a length of ten foot should be lowered to the hole. If a small open bucket fitted to the end will make the rescue more fast. The kitten will enter the bucket, or will try to climb up the rope.</span>
Answer:
blue
You see white. What happens when you shine cyan light on a magenta shirt? You see blue.
Explanation:
Okay so i believe that potential energy is mechanical but there are two answers with potential energy in it. Its a tough one but I think I would go with gravitational potential energy.
Hope this helped!
