Make vthe subjject of the formulaE=mvsquare/ 2
find the value of v when m =2 and E=64​

E=mv²

divide both sides by m

E/m=v²

square root both sides

v=√E/m

m=2,E=64

v=√64/2

v=9/√2

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
