Question

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%​

Answer 1

Answer:

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%
