A force of 880 newtons stretches a spring 4 meters. A mass of 55 kilograms is attached to the end of the spring and is initially released from the equilibrium position with an upward velocity of 12 m/s. Find the equation of motion.

Carbon-14 undergoes radioactive decay in the reaction above. determine the type of radiation emitted in this reaction and describe what is happening to the nucleus during this reaction. a) alpha radiation is emitted in this equation because the atomic number increases (from 6 to 7). this means a helium atom has been emitted from the nucleus. b) beta radiation is emitted in this equation because the atomic number increases (from 6 to 7). this means a neutron has decayed into a proton, which occurs by emitting an electron. c) beta radiation is emitted in this equation because the atomic number increases (from 6 to 7). this means a neutron has decayed into a electron, which occurs by emitting an proton. d) gamma radiation is emitted in this equation because the atomic number increases (from 6 to 7). this means a neutron has decayed into a proton, which occurs by emitting an electron. the answer is not cthe answer is b
