The total mechanical energy of an object with mass m at height h in a closed system can be written as . Solve for v, the velocity of the object, in terms of the given quantities. v =

v=

Step-by-step explanation:

total energy=k.e+p.e

M.E-P.E=K.E

SOLVINGG FOR VELOCITY

=2(M.E-P.E)/m

v=\sqrt2(M.E)/m -gh

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
