Kinetic energy varies jointly as the mass and the square of the velocity. a mass of 15 grams and velocity of 3 centimeters per second has a kinetic energy of 27 ergs. find the kinetic energy for a mass of 5 grams and velocity of 9 centimeters per second.

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b
