Mechanical energy = potential energy + kinetic energyThe ball is on the ground so has no potential energy.
M.E = K.EM.E = 1/2 mv²M.E = 1/2 x 1 x 2²M.E = 2 J
thanks again and have to go to the store and get some rest I will be there at puno my phone is not working and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about the week and I have a few questions about you
Answer:
<h2>15 Ns</h2>
Explanation:
The impulse of an object can be found by using the formula
impulse = force × time
From the question we have
impulse = 0.5 × 30
We have the final answer as
<h3>15 Ns</h3>
Hope this helps you
Current= V/R
C=60 volts/12 ohms
C= 5 amperes
Hope I helped :)
