TK:

an ice skater starts with a velocity of 2.25 m/s in a 50 degree direction. after 8.33 s she is moving at 4.65 in a 120 degree direction. what is the x component of her acceleration

Vocaloid:

hm. physics really isn't my strongest subject but I can give it a shot. acceleration = change in velocity/time since we only want the x-direction 4.64cos(120) - 2.25cos(50) then divide this quantity by the time (8.33seconds)
