The relationship between energy e possessed by an object of mass m kg travelling with speed of v m/s is given by the formula e =1/2 mv².
express m in terms of e and v and find the mass of an object whose energy and speed are 1800 joules and 25 m/s, respectively?

m = 5.76 Kg

Step-by-step explanation:

Given

E = mv²

Multiply both sides by 2 to clear the fraction

2E = mv² ( divide both sides by v² )

= m

When E = 1800 and v = 25, then

m = = = 5.76 Kg

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
