Calculating Acceleration A football player kicks a 0.94 kg football with a force of 2.4 N.

Calculate the acceleration of the football as the player kicks the ball. Round your answer to the nearest tenth of a m/s2.

Which units can be used to measure length or distance? check all that apply. gram meter kilometer liter inch

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)
