Aperson absentmindedly walks off the edge of a tall cliff. they will fall 50 m into either
deadly rocks or a safe lake below the cliff. the lake is 12 meters away from the edge of
the cliff
if the person walks off the cliff at a constant velocity of 3.8 m/s,
will they survive? no (yes or no) how far did they go?

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33
