Estimate the velocity and percentage relative error
The velocity of falling parachute is computed as:
v(t)=(gm)/c (1-e^-((c/m)t))
Where, g=9.8m/s2; m=
50kg; c=12.5.
Use 3 terms of Taylor series to estimate the velocity at t=6sec using v(t=0). What is the percentage relative error.
Expected delivery within 24 Hours
The velocity of point P relative to frame A is vp/A = (-14.9 i + 19.4 J) ft/s and the acceleration of P relative to frame B is ap/B = ( 3.97i + 4.79j) ft/s/s.
