Can you please help me with this question.My answers are wrong.thank you so much for your time

Att = 478 s after midnight, a spacecraft of mass 2500 kg is located at position m, and at that time an asteroid whose mass is 8 x 1015 kg is located at position m. There are no other objects nearby. Part 1 (a) Calculate the (vector) force acting on the spacecraft. F net = N Save for Later Attempts: 0 of 10 used Submit Answer Part 2 (b) Att = 478 s the spacecraft's momentum was p;, and at the later time t = 485 s its momentum was p f. Calculate the (vector) change of momentum P f - Pi. P s - Pi = kg.m/s e Textbook and Media
