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 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.
a) When do the two balls pass each other?
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?

A ball of mass 60 g is dropped from a height of 3.4 m.
It lands on the top of a ramp at height 1.8 m with a kinetic
friction coefficient of .3. The ramp is tilted at an angle of 20
degrees.
(a) What is the velocity of the ball at the top of the
ramp?
(b) At the bottom of the ramp it collides with and
sticks to a ball of mass 73 g. What is their velocity...

A ball is dropped from a building of height 100m. At the same
time, another ball is then thrown vertically up from the ground
with a velocity V0. They meet each other at
the middle. What is the speed V0 of the ball thrown
vertically up?
a) 44.3m/s
b)9.8m/s
c) 31.3m/s
d)19.6 m/s
e) 98.0m/s

A ball rolls down from the top of an incline with a height of 5
m high without slipping. The ball has a diameter of 0.2m. What are
the ball’s translational speeds a) at the center of the ball, b) at
the contact point on the ground, and c) at the top of the ball when
it arrives at the bottom? What values of "c" do you expect for
hollow/solid balls? Will the hollow ball be faster?

If dropped
together from a height h,
how high does a tennis ball on top of a basketball bounce (tennis
ball’s mass is much smaller than basketball’s mass) ?

i am dumb lol please explain like you are explaining to a little
kid. do not write in cursive)

A soccer ball is kicked from the top of one building with a
height of H1 = 30.1 m to another building with a height
of H2 = 10.8 m. (It is not a very smart idea to play
soccer on the roof of tall buildings.)
The ball is kicked with a speed of v0 = 19.3 m/s at
an angle of θ = 74.0° with respect to the horizontal. The mass of a
size 5 soccer ball is m...

A boy standing on top of a building throws a small ball from a
height of H1 = 45.0 m. (See figure.) The ball leaves
with a speed of 26.9 m/s, at an angle of 61.0 degrees from the
horizontal, and lands on a building with a height of H2
= 12.0 m. Calculate for how long the ball is in the air. (Neglect
air friction, and use g = 9.81 m/s2.)

1)A 861 g rubber ball is dropped from height 15.1 m, and it
rebounds to height 3.15 m. Assuming there is no air friction, find
the magnitude of the impulse, in N-s, exerted by the ground on the
ball.
2)Milly (mass 98.7 kg) runs at 2.73 m/s along the positive
x-axis and then jumps onto a stationary 278 kg box. Milly
and the box slide across the floor for distance 0.357 m, and then
they come to a stop. Find...
An object with mass m = 0.6 kg is dropped from the top of the building...
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...
