$An object begins to move along the $ y $ axis and its position is given by the equation $ y=5 t^{2}-3 t-2 $, with $ y $$ $Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground \( 3.72 \mat$

An object begins to move along the $ y $ axis and its position is given by the equation $ y=5 t^{2}-3 t-2 $, with $ y $ in meters and $ t $ in seconds. (Express your answers in vector form.) (a) What is the position of the object when it changes its direction? m (b) What is the object's velocity when it returns to its original position at $ t=0 $ ? $ \mathrm{m} / \mathrm{s} $ Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground $ 3.72 \mathrm{~s} $ later. (a) If the speed of sound in air is $ 343 \mathrm{~m} / \mathrm{s} $ at the rock climber's location, what is the depth of the chasm? $ \mathrm{m} $ (b) What is the percentage of error that would result from assuming the speed of sound is infinite? $ \% $
