horizontal displacement mg relative to the ground (hom its

launch position to its landing position) is measured. Figure 44%

gives Arm as a function of up Assume the ball lands at approch-

motely its launch height. What are the values of (a) um and (b)

way? The ball' s displacement Aza, relative to the sled can also be

measured. Assume that the sled' s velocity is net changed when

the ball is shet. What is Aza, when v, is (c) 5. mls and (d) 15 mls?

along the following course: so km/ h for 2. min, tum 900 to the

how far are you from your starting point, and (b) in what direction

relative to your initial direction of travel are you?

rectal from the east. At first conservation, the airplane is at distance

360 m hem the station and at angle all = 400 above the heri-

zen. The airplane is tracked through an angular change Ag = 1230

in the vertical east -west plane; its distance is then = 790 m. Find

the (a) magnitude and (b) direction of the airplane' s displacement

during this period.
