Ask Your Teacher A constant force of 2.0 N to the right acts on a 20.0 kg mass for 0.35 s. (a) Find the final velocity of the mass if it is initially at rest. .035 Correct: Your answer is correct. m/s (b) Find the final velocity of the mass if it is initially moving along the x-axis with a velocity of 1.31 m/s to the left.

If an atom contains 11 protons in its nucleus, predict the element with the atomic number and electronic configuration. will the number of electrons remain the same during the chemical reaction in such an atom? explain.

The slope of a velocity time graph over any interval of time gives the during that interval
