At a given instant, the football player at A throws a football C with a velocity v0=20+last digit of your Student ID number (SID) (in m/s) (eg. for SID=54300456?, v0=20+7=27 m/s) in the direction shown. Player 8 is 15 m away from A and runs at a constant speed when A starts to throw the football. Determine: a) The constant speed at which the player at B must run so that he can catch the football at the same elevation at which it was thrown. in) The relative velocity and acceleration of the football C with respect to player 8 at the instant the catch is made
