Answer:
An object’s weight is proportional to its mass.
Answer:
a.)How far from the building does the ball hit the ground?
72 m
b.)How long does it take to hit the ground?
6 s
c.)What is its speed when it hits the ground?
63.48 m/s
Explanation:
When an object is in free fall with no air resistance present or wind acting on it it only is under the influence of gravity. Gravity acts straight down and accelerates the object all the way to the ground. If there is air resistance or a wind force on the object it will have an acceleration that isn't 9.8 m/s^2

Answer:
(a) 2.03 m/s
(b) 2.15 m/s
Explanation:
(a)
From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum
Momentum, p=mv where m is the mass and v is the velocity
where
is the common velocity,
and
are velocities of the first railroad car and the second railroad car respectively,
and
are masses of the first railroad car and the second railroad car respectively
Substituting the given figures then

(b)
Momentum, p=mv where m is the mass and v is the velocity
where
and
are initial velocities of the ball moving towards west and the other ball moving in opposite direction respectively,
and
are masses of the first railroad car and the second railroad car respectively
Taking west as positive then the opposite direction will be negative hence

Note that when the 0.455 rebounds, it moves towards East and since we took West as positive that is why we give 15.4 as a negative value.
towards East
