A car is traveling at 33.2 m/s. If the car has a kinetic energy of 688,900 J, what is the car's mass?
2 answers:
Answer:1250kg
Explanation:
Kinetic energy(ke)=688900j
Velocity(v)=33.2m/s
Mass(m)=?
ke=(mv^2)/2
688900=(mx(33.2)^2)/2
688900x2=mx1102.24
1377800=mx1102.24
m=1377800/1102.24
m=1250kg
Answer:
1250kg
Explanation:
= 625
625 x 2 = 1250

wow i have know idea
Explanation:
You can decrease the mass, or you can increase the force applied to the object
it's 1727 +822 just kidding
Answer:
Visible Light
wavelength = 4000 - 7000 Angstroms = 400 - 700 milli-microns
1 A unit = 10^-10 m
1 mμ = 10^-9 m
It becomes a different element
