Find the velocity of mass mB after the collision. Assume no outside force acts on the two masses during the collision. Enter the x, y, and z components of the velocity separated by commas. Express your answer to two significant figures.

How would doubling the made of an object change the objects potential energy

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius
