Answer:
i believe he threw the ball up at about 18 mph
Explanation:
Answer:
Vf = 41.6 [m/s].
Explanation:
To solve this problem we must use the equations of kinematics.
Vf² = Vo² + (2*g*y)
where:
Vf = final velocity [m/s]
Vo = initial velocity = 0
g = gravity acceleration = 9.81 [m/s²]
y = height = 88.2 [m]
Note: The positive sign of the equation tells us that the acceleration of gravity goes in the direction of motion.
Vf² = Vo² + (2*g*y)
Vf² = 0 + (2*9.81*88.2)
Vf = (1730.48)^0.5
Vf = 41.6 [m/s]
According to the solving, the volume that this gold nugget occupies is 1.29 cm³.
<h3>What is volume?</h3>
Volume is a standard measure of three-dimensional space that is occupied. It is typically mathematically represented using standard or SI-derived units. Volume and the concept of length are connected. It is sometimes referred to as the object's capacity.
d= m/ V
m= dV
V= m/d
<h3>So according to the given data,</h3>
The mass of the gold nugget is 25 grams.
The density of gold is 19.32 g/cm³.
We know that,
m= Vd
To find out the Volume(V),
V= m/d
V= (25 g)/(19.32 g/cm³)
V= 1.29 cm³.
According to the solving, the volume this gold nugget occupies is 1.29cm³.
