Answer:
y = 3.16 m
Explanation:
Once thrown straight up, the only influence on the ball is gravity, which acts slowing down the ball.
In absence of gravity, the ball had moved forever with the same initial velocity, so the displacement at a time t had been as follows:
y = v₀*t
Due to the action of gravity, the actual displacement is less than this value, and can be calculated with the following equation:
Replacing by v₀ = 12. 0 m/s, t = 0.300 s, and g = 9.8 m/s², we can solve for the vertical displacement, as follows:
So, the position (taking the origin coincident with the point where the ball leaves the hand), is just the vertical displacement we have just found.
⇒ y = 3.16 m
Answer:
In the given equation y=Asin(ωt−kx)
Since, trigonometric function is a dimensionless quantity. So, (ωt−kx)is also dimensionless quantity.
So,
(ωt−kx)=1
ωt=1
[ω]= <u>1</u>=[T] ^−1
[T]
kx=1
[k]= <u>1</u>=[L]^ −1

Answer:
Duration of the total trip
Explanation:
Acceleration is defined as the rate of change of velocity of an object:
where
is the change in velocity
is the duration of the change in velocity
Acceleration is measured in meters per squared seconds, . Also, we should note that acceleration is a vector quantity, so in order to completely define acceleration we also need to specify the direction.
<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
