Answer:

22.5kg

Explanation:

Since we not told wat to find, we can as well find the mass of the beaver.

Kinetic energy formula is expressed as;

KE = 1/2mv²

m is the mass

v is the speed

Given

KE = 45Joules

v = 2.0m/s

Substitute into the formula and get the mass

45 = 1/2m(2)²

45 = 2m

m =45/2

m = 22.5kg

Hence the mass of the beaver is 22.5kg
