D=44.13, Horizontal velocity is unimportant. The time it takes the cannon ball to fall to the ground is the key to determining the height of the cliff. where that cannon is present.
The speed of any projectile travelling along a Horizontal velocity is known as the horizontal velocity. When a particle or object is launched into the air at an angle other than 90 degrees, it moves along the trajectory path and changes the shape of the curve to a parabolic one.
the speed at which velocity changes over time. Due to its magnitude and direction, acceleration is a vector quantity. The first derivative of velocity with respect to time or the second derivative of position with respect to time are further examples. This is called acceleration.
Distance to the ground is d = 1/2gt^2,
where g is the acceleration rate of gravity (9.80665 m/s^2)
and t = 3 secs.
d = .5×9.80665×9 = 44.13 m.

It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, the answer to the given statement is FALSE. Pigments are NOT always made of natural materials. Pigments can either be man-made or the one that occurred naturally as what you see in our environment. Hope this helps.
Ke=1/2mv^2
Ke= 0.5*30*20^2
Ke= 6000joules
Answer:
1.05045 kg/m³
Explanation:
= Density of air = 1.26 kg/m³
= Density of hot air
= Mass of balloon = 539 kg
g = Acceleration due to gravity = 9.81 m/s²
v = Volume of air in balloon = 
The net force on the balloon will be
Also
The density of hot air inside the envelope is 1.05045 kg/m³
