A rocket is departing Earth towards Mars. The following function represents the rocket's vertical velocity for the first 3 hours: +3 v(t) = t e 13t 13' in km/h. (a) Approximate the distance travelled by the rocket in the first 3 hours using a right-hand Riemann sum with 4 intervals: Distance (b) Approximate the velocity function with a Taylor polynomial of degree 2 centred at a = 0: km. v(t) 0 + t + 0+0+0. +2 (c) Use the polynomial approximation to obtain a new approximation of the distance travelled by the rocket in the first 3 hours: Distance km. (d) Calculate the exact distance travelled by the rocket in the first 3 hours: Distance= km.
