A projectile is fired horizontally with speed v0 from the top of a cliff of height h. Itimmediately enters a fixed tube with length x, as shown in Figure. There is friction between the projectileand the tube, the effect of which is to make the projectile decelerate with constant acceleration ax. After theprojectile leaves the tube, it undergoes normal projectile motion down to the ground. Calculate the totalhorizontal distance, l, that the projectile travels.

As part of a department store display, a model train D runs on a slight incline between the store’s up and down escalators. When the train and shoppers pass point A, the train appears to a shopper on the up escalator B to move downward at an angle of 22° with the horizontal, and to a shopper on the down escalator C to move upward at an angle of 23° with the horizontal and to travel to the left. Knowing that the speed of the escalators is 3 ft/s, determine the speed and the direction of the train.
