Question

Question 3) The diagram is about the motion of an object in the xy plane: Overall the object starts at point A on the +y axis, moves in the-y direction until reaching the origin of coordinates where it makes a right angle turn and moves in the +x direction until reaching point D on the x-axis. The speed is not constant and we know more detail about the motion at only four points: When t-0.00s] it is at point A which has coordinates x-0.00(m) and y 100.0(m] and it is moving with velocity (in the-y direction) = 12.00 o When t 10.0s it is at point B which has coordinates x-0.00(m] and y 40.0[m] and it is moving with velocity i = 6.00(in the -y direction) o Whent-20.0s] it is at point C which has coordinates x 40.0[m] and y-0.00[m] and it is moving with velocity e = 6.00 (in the +x direction) When t 30.0(s] it is at point D which has coordinates x-100.0(m] and y 0.00[m] and it is moving with velocity i = 12.00 (in the +x direction) AO C D a) Find the average acceleration of the object for the portion of the trip from point A to point B Direction Magnitude b) Find the average acceleration of the object for the portion of the trip from point A to point c Direction Magnitude c) Find the average speed of the object for the portion of the trip from point B to point D Average speed d) Find the average velocity of the object for the portion of the trip from point B to point D Magnitude Direction -_ e) Find the average velocity of the object for the portion ef the trip from point C to point D Direction Magnitude 2.
