What are the specific uses of Uranium-238 (the particular isotope) with its benefits and careers that use it?

true tan speed = ang vel x radius

conservation of mass

mass before something happens = mass afterwards

98.4 m

explanation:

let s = distance up the plane  

then by conservation of energy  

1/2m(18.3)^2 = mg s sin(10)  

(18.3)^2 = 2g s sin(10)  

s = (18.3)^2/2gsin(10)  

= 98.39564526  

= 98.4 m
