Law of conservation of mass
Explanation:
Answer:
sound of electronic means
Answer:
<h2>9.48*10^-5J</h2>
Explanation:
Step one:
given data
mass of ball m=0.43kg
speed v= 75m/h >>>>> to m/s = 75*0.00027
v =0.021m/s
Required
the kinetic energy KE
Step two
applying
KE= 1/2mv^2
KE= 1/2*0.43*(0.021)^2
KE= 0.5*0.43*0.0004.41*10^-4
KE=0.000094815
KE=9.48*10^-5J
The kinetic energy is 9.48*10^-5J
The answer is in the image.
