Extracted text: a. If the Pressure produced by the gas cylinder of the motor of the rocket is governed by the below equation: P = sin (V)cos (V) And the energy is given by: v2 W =| PdV Jvi If V2=2V1, Find W. What will be W if V2=4V1. i. ii. iii. Use Matlab or excel to plot the Energy in the interval [0,21] b. If the vibration at the boundaries of the piston of the motor is given by: v(t) = at + b; a, b are constants, you may choose any integer value not equal to zero for any of them. v(t) = te(-t). i. v(t) = 5sin(2at) cos(4wt) find the average and rms vibration for each case: i. ii. Vavg v(t)dt VRMS = - v²(t)dt
