An object with mass m = 0.6 kg is dropped from the top of the building and falls 21 m down in front of the cafe.
1.1 Calculate the speed of the object as it hits the ground and calculate the time for the fall. Neglect in this question the air resistance.
In a more accurate calculation we need to take air resistance into account. In a wind tunnel the air resistance of the object has been measured giving rise to an acceleration of: aair = 0.03v2 where v is the speed of the object.
1.2 Now, taking air resistance into account, find the speed of the object as it hits the ground. Any integrals in your calculation should be calculated by hand!
1.3 Calculate the time of the fall when air resistance is taken into account. (You are allowed to use calculator to calculate occurring integrals when answering this question!)

5. A ball is dropped from the top of the building
whose height is 60 m. At the same time, another
ball is thrown up from the ground with a velocity of 25 m/s.
i) At what distance from the top do the balls cross each
other?
ii) How much time does the two balls take to cross each
other?
iii) What is the maximum height does the second ball reach?

A container with mass m kg is dropped by a helicopter from height h km at...
A container with mass m kg is dropped by a helicopter from
height h km at time t=0, with zero velocity. from the outset, its
fall is controlled by gravity and the force of air resitance, f(v)=
-kv, where v is the current velocity of the container. in t seconds
after the drop, a parachute opens, resulting in an increase of air
resistance up to f(v) = -kv. determine the time t at which the
container touches the ground. and...

A ball is dropped from rest from the top of a
building of height h. At
the same instant, a second ball is projected vertically upward from
ground level, such that it has zero speed when it reaches the top
of the building.

Answer it in terms of h.
b)Which ball has greater speed when they are
passing?
c)What is the height of the two balls when they
are passing?

An object of mass 2 kg is released from rest from a platform 30
m above the water and allowed to fall under the influence of
gravity. After the object strikes the water, it begins to sink with
gravity pulling down and a buoyancy force pushing up. Assume that
the force due to gravity (g = 9.81 m/s2) is constant, no change in
momentum occurs on impact with the water, the buoyancy force is 1/2
the weight (weight=mg), and the...
