Please explain every step required to solve the following question
Question-A soccer ball has a mass of 0.40kg. Initially it is moving to the left at 20. m/s, but then it is kicked and given a velocity at 45o upward and to the right, with magnitude 30. m/s. Find the impulse that acted on the soccer ball and the average net force that acted on it (magnitude and direction), assuming a collision time 0.010 s.
