1. Find the integral Solxz by the Trapezoidal rule with 9 points. 2. is A particle of mass m moving through a fluid subjected to a viscous resistance R, which is a function of the velocity v. The relationship between the resistance R, velocity v, and time t is given by the equation - 772 du. R(V) Vo Suppose that R(V) = -1 v for a particular fluid, where R is in newtons and v in m/s. If m = 5 kg and vo 12 m/s. approximate the time t required for the particle to slow to vi = 8 m/s using Trapezoidal rule with 8 subintervals. 3. Use Lagrange interpolating polynomial to determine yat x- 8 to the best possible accuracy. O 2 5.5 11 0.5 3.134 5.3 9.2 10.2
