The following data was collected for the distance traveled versus time for a rocket: t, s 0 15 30 45 60 75 y, km 0 1.69 7.19 17.2 32.3 53.3 Use numerical differentiation to estimate the vertical component of the rocket’s velocity and acceleration at t = 0, t = 30, and t = 60 seconds. At each time, use the least computationally expensive algorithm with an O(h4 ) error. The numerical differentiation formulae can be found on the equation sheet.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
