Which is an example of observational learning? tristan is sure he'll get caught if he sneaks tv time while his mom is out shopping, so he decides not to do it. sylvia watches her mom put a napkin on her lap during restaurant dining, so she does the same. kanu hears a song on the radio and buys the cd so she can play it repeatedly. trey plays with his sisters in the backyard, and he swings from a rope ladder to pretend he is tarzan.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
