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...

A speedboat starts from rest with a constant acceleration of +1.50 m/s2. After 4.00 seconds, its acceleration changes to +1.00 m/s2. After another 5.00 seconds, its acceleration changes to zero and the boat travels with constant velocity for a further 10.0 seconds. The boat then slows down and stops by accelerating at -2.00 m/s2. 1. Calculate the velocity and displacement of the boat at t = 4.00 seconds. 2. Calculate the velocity and displacement of the boat at t =...
