Calculate the displacement (magnitude and direction) of the ball when it is moved from the initial to the final position.initial position (x, y)i = (–10.0, 10.0) mfinal position (x, y)f = (15.0, –10.0) m?

Answered By Majid B

displacement vector = final position - initial position =((xf - xi) , (y- yi))= (15 - (-10) , -10 - 10) = (25 , -20)

displacement magnitude = sqrt (252 + (-20)2) = 32.0 m

displacement direction = tan-1(-20 / 25) = -38.7 degrees
