Answer:
The answer to the question is
The ball will go 0.14 meters high if the gun is aimed vertically
Explanation:
The energy in the spring → Energy, E =
Where E = energy in the spring
k = Spring constant
x = Spring compression or stretch
Therefore E =
The spring energy is transferred to the ball as kinetic energy based on the first law of thermodynamics which states that energy is neither created nor destroyed
Kinetic energy = KE =
From which v = = = 1.66 m/s
from v² =u² - 2·a·S
Where v = final velocity = 0 m/s
u = initial velocity = 1.66 m/s
a = g = Acceleration due to gravity
S = height
Therefore 0 = 1.66² - 2×9.81×S
or S = 1.66² ÷ (2×9.81) = 0.14 m
Answer:
y = 60 mph
Explanation:
given,
average speed of Sarah driving from Orlando to Tampa = 30 mph
average speed of return = ?
whole trip average speed = 40 mph
now,
Let x be the distance from Orlando to Tampa
y be the speed of return
60 + 2 y = 3 y
y = 60 mph
hence, speed of the return is equal to 60 mph.
No it isn't because acceleration is the <span>increase in the rate or speed of something.</span> It's going at a constant rate.
Answer:
True.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Simply stated, a vector quantity has both magnitude and direction.
Thus, a vector quantity is: A deer running 15 meters per second due west.
