A rock is dropped from the top of a tall tower. Half a second
later another rock, twice as massive as the first, is dropped.
Ignoring air resistance,
they strike the ground with the same kinetic energy
they strike the ground more than half a second apart.
the distance between the rocks increases while both are
falling.
the acceleration is greater for the more massive rock.

4. Falling Drop A raindrop of mass \(m_{0}\), starting from rest, falls under the influence of gravity. Assume that as the raindrop travels through the clouds, it gains mass at a rate proportional to the momentum of the raindrop, \(\frac{d m_{r}}{d t}=k m_{r} v_{r}\), where \(m_{r}\) is the instantaneous mass of the raindrop, \(v_{r}\) is the instantaneous velocity of the raindrop, and \(k\) is a constant with unit \(\left[m^{-1}\right] .\) You may neglect air resistance.(a) Derive a differential equation for the...

In this lab, an apple is released from rest and falls freely
until it lands in a bowl. Watch the video here. We will be
measuring y (the vertical position coordinate) as a function of
time t. Notation: y0 is the value of y at t = 0; vy is the
y-component of the velocity; vy0 is the value of vy at t = 0; ay is
the y-component of the acceleration. The +y-direction is up.
Assuming air resistance is...

An
apple drops from the tree and falls freely. The apple is originally
at rest a height H0 above the ground. The ground is covered with a
thick lawn, which is made of blades of grass of height h. When the
apple enters the grass, it slows down at a constant rate so that
its speed is 0 when it reaches ground level.
A. Find the speed of the apple just before it enters the
grass.
B. Find the acceleration...

level at time t.

(b) How long does it take the stone to reach the ground?
(Round your answer to two decimal places.)
(c) With what velocity does it strike the ground? (Round your
answer to one decimal place.)
(d) If...

A particle of mass m moves under the influence of gravity g on
the inner surface of a smooth cone of half-angle α. The axis of the
cone is vertical, with its vertex downward. (a) Find the
equation(s) of constraint of the system. (b) Find Lagrange’s
equations of motion using the method of undetermined multipliers.
(c) Determine the condition on the angular velocity ω such that the
particle can describe a horizontal circle at a height h above the
vertex.

On
the moon the acceleration due to gravity is -1.6 m/s. a stone is
dropped from a cliff on the moon and his the surface of the moon 40
seconds later.

a. Consider a (spherical) pebble of radius 1 cm falling under
the influence of gravity. Assume it experiences a quadratic drag
force (i.e., proportional to the velocity squared). Assume the
constant of proportionality for the drag force is the product of a
constant κQ and a geometric factor is the square of the radius.
Assume the density of stone is 2500 kg/m3 and that κQ = 0.87 kg/m3
. Estimate the terminal velocity of the pebble (vT ). b. Consider...
