What is the spacecraft interplanetary velocity (in km/s) with respect to the Sun when arriving near Mars?

Recall that your trip to Mars is accomplished by using an elliptic transfer orbit going from Earth to Mars as shown in Fig. 1. This trajectory umes that Earth at departure, the Sun, and Mars at arrival, are aligned. You calculated that the semi-major axis and the eccentricity for this transfer orbit was a= 187848253000 m and e= 0.206 , respectively, What is the spacecraft interplanetary velocity (in km/s) with respect to the Sun when arriving near Mars
