The tower of Pisa is 54.5 m tall. Assuming that Galileo dropped his object from rest from the top of the tower and that the effects of air resistance were negligible, how long would it have taken the object to fall?

A man enters a tall tower, needing to know its height. He notesthat a long pendulum extends from the ceiling almost to the floorand that its period is 18.0 s. How tall is the tower? If thispendulum is taken to the Moon, where the free-fall acceleration is1.67 m/s2, what is the period there?

 A 10-kg lead brick is dropped from the top of a 629-m-tall television transmitting tower in North Dakota and Falls to the ground. Assuming all of its energy goes to heat it, what is its temperature increase.

 

Consider a tall building located on the Earth’s equator. As the Earth rotates, a person on the top floor of the building moves faster than someone on the ground with respect to an inertial reference frame because the person on the ground is closer to the Earth’s axis. Consequently, if an object is dropped from the top floor to the ground a distance h below, it lands east of the point vertically below where it was dropped. (a) How far to the
east will the object land? Express your answer in terms of h, g, and the angular speed ω of the Earth. Ignore air resistance and assume the free-fall acceleration is constant over this range of heights. (b) Evaluate the eastward displacement for h = 50.0 m. (c) In your judgment were we justified in ignoring this aspect of the Coriolis effect in our previous study of free fall? (d) Suppose the angular speed of the Earth were to decrease due to tidal
friction with constant angular acceleration. Would the eastward displacement of the dropped object increase or decrease compared with that in part (b)?
