Ablock of unknown mass is attached to a spring of spring constant 6.8 n/m and undergoes simple harmonic motion with an amplitude of 9.2 cm. when the mass is halfway between its equilibrium position and the endpoint, its speed is measured to be 25.7 cm/s.
(a) calculate the mass of the block.
(b) calculate the period of the motion.
(c) calculate the maximum acceleration of the block.

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
