In the table given below, experimentally obtained velocity (dependent variable) vs time (independent variable) data is provided. Please answer the following questions using the data. Time (t) Velocity (v) 0.0 0.8 2 1.4 3 2.1 4 2.6 3.3 7 3.9 9. 4.9 10 6.0 12 8.6 14 14.4 a) What is the total displacement betweent = 0- 14 seconds. Please note that displacement is obtained via X = S V dt. Please use a combination of numerical integration methods and prefer to use as many as high accuracy methods as possible. b) Please calculate the acceleration at t = 2 seconds using the most accurate method %3D dv possible. Please note that acceleration is obtained via a = dt c) Please calculate the acceleration at t = 14 seconds using the most accurate method dv possible. Please note that acceleration is obtained via a = dt

this is my data i need to creat a scatter plot on execel and approximate the year that penny composition started to changing . i know how to do the plot i just dont know to find approximation . thanks  Year Mass (g) 1990 2.4822 1994 2.5055 2006 2.5914 1991 2.4852 1998 2.5201 1971 3.1439 1984 2.5132 2006 2.4852 1994 2.5076 1979 3.1024 1975 3.0668 1982 3.0776 2001 2.4873 1989 2.532 1974 3.1034 1980 3.0917 2000 2.4921 1977 3.1057 1993 2.5005 1968 3.0943 1982 3.0761 2000 2.5061 1975 3.093 1981 3.1011 2008 2.489 1987 2.5068 1976 3.1 2010 2.4836 1999 2.5458 2007 2.5015 1987 2.5143 1978 3.0798 1995 2.4947 1974 3.0307 1981 3.0939 1992 2.4737 1982 3.935 1972 3.0973 1993 2.4898 1998 2.4951 1991 2.4756 1995 2.5061 1994 2.4949 2007 2.514 1996 2.4905 2001 2.5073 2002 2.4976 2006 2.5118 1996 2.5159 1972 3.0513 1994 2.4941 1990 2.4832 2007 2.4744 2007 2.4804 1976 3.0947 2001 2.5391…
