The equation of motion for a particle moving along the y-axis is given as y(t) = 3t2 - 6t + 2 for t2 0. Part A: Find the velocity and acceleration functions. (10 points)
Part B: Describe where the particle changes direction and the intervals where the particle speeds up or slows down. (20
points)

conservation of mass

mass before something happens = mass afterwards

amplitude

hope this

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
