You find yourself in the middle of a frozen lake with a surface so slippery (ms = mk = 0) you cannot walk. however, you happen to have several rocks in your pocket. the ice is extremely hard. it cannot be chipped, and the rocks slip on it just as much as your feet do. can you think of a way to get to shore? use pictures, forces, and newton’s laws to explain your reasoning.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
