Q4) A particle moves from the point (-2,-6) to the point (3, 5) in the (x, y) plane (all units measured in metres).
a. Write down the displacement vector d which describes its motion and calculate la
b.
If the motion takes 3s, assuming that the particles speed is constant, write down the velocity vector v. Hint: for a
constant speed, the velocity is equal to the distance divided by the time.
Finally, calculate the speed
of the particle
C.
