1.7. If a marble is launched straight upward at a speed of 15 m/s and doesn't hit anything on its way up or down, it will reach a height of about 11.5 m above the launch point before it starts falling back down, and exactly 2.0s after launch, it will be 10.4m above the launch point and moving downward at a speed of 4.6 m/s. Calculate the (a) distance traveled, (b) displacement, (c) average speed, and (d) average velocity of the marble during the 2.0s after launch. 1.7.
