6) A force Fis exerted on a 5 kg block to move it across a rough surface, as 1 point

shown. The magnitude of the force is initially 5 N, and the block moves at a

constant velocity. While the block is moving the force is instantaneously

increased to 12 N. How much kinetic energy does the block now gain as it

moves a distance of 2 m?*

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. which statement is true for this reaction?

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
