The eiffel tower is made of iron and is about 300 m tall. due to thermal expansion, its height changes between winter and summer. estimate the height change the tower undergoes if the difference in temperature between the seasons is 23º c. enter your answer in meters but do not include units. provide your answer to the hundredths place.

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
