A 398-kg boat is sailing 14.0° north of east at a speed of 1.50 m/s. 23.0 s later, it is sailing 33.0° north of east at a speed of 4.40 m/s. During this time, three forces act on the boat: a 32.8-N force directed 14.

Match the type of metamorphism to its best definition. Impact metamorphism ? The process in which a rock changes as a result of heat generated from magma. Dynamic metamorphism ? The process in which a rock changes due to pressure directed on it.
