The cloud would most likely get bigger in size. If humidity is high, there is a lot of water avalible to be made into a cloud. The larger the amount of water, the more clouds that can form.

Complete Question:
A basketball player tosses a basketball m=1kg straight up with an initial speed of v=7.5 m/s. He releases the ball at shoulder height h= 2.15m. Let gravitational potential energy be zero at ground level
a) Give the total mechanical energy of the ball E in terms of maximum height hn it reaches, the mass m, and the gravitational acceleration g.
b) What is the height, hn in meters?
Answer:
a) Energy = mghₙ
b) Height, hₙ = 5.02 m
Explanation:
a) Total energy in terms of maximum height
Let maximum height be hₙ
At maximum height, velocity, V=0
Total mechanical energy , E = mgh + 1/2 mV^2
Since V=0 at maximum height, the total energy in terms of maximum height becomes
Energy = mghₙ
b) Height, hₙ in meters
mghₙ = mgh + 1/2 mV^2
mghₙ = m(gh + 1/2 V^2)
Divide both sides by mg
hₙ = h + 0.5 (V^2)/g
h = 2.15m
g = 9.8 m/s^2
V = 7.5 m/s
hₙ = 2.15 + 0.5(7.5^2)/9.8
hₙ = 2.15 + 2.87
hₙ = 5.02 m
Answer:
The object keeps moving at the same speed and direction.
Explanation:
This is because the balanced forces acting on the object cancel out each other since the are in opposite directions, leaving only the original force acting on the object which is causing its motion.To illustrate, let F₁ be the initial force and F₂ and F₃ be the balanced forces. The net force F = F₁ + F₂ + F₃. Since F₂ and F₃ are balanced, F₂ = -F₃ ⇒ F₂ + F₃ = 0.
So,
F = F₁ + F₂ + F₃
= F₁ + (F₂ + F₃)
= F₁ + 0
= F₁
Which is the original force acting on the object. Thus, the object keeps moving at the same speed and direction
