the energy E posessed by a moving object of mass M and velocity V. varies as it's mass and the square of its velocity. (a)..write down the equation connecting E, M and V..(v)what would be the % change in energy when v us increased by 20% and M is decreased by 15%

Energy of a mass M varies as it's mass, M, times the square of its' velocity, or E=MV�

b. If V is increased by 20%, then E changes by (1+.2)�-1, or +44%. If M is decreased by 15%, then E=((1-.15)M)V�, or E decreases by 15%

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
