The object's speed will remain constant after the it leaves his hand.
So will HIS speed in the opposite direction.
Answer:

Explanation:
given,
s = 400- 16 t²
we know,
Velocity of an object is defined as the change in displacement per unit change in time.
velocity an also be return as




Hence, instantaneous velocity function given by 
To calculate instantaneous velocity, you need to insert value of time.
ex, instantaneous velocity at t = 4 s
v = -32 x 4 = -128 m/s.
Answer:
vf = 0
Explanation:
Since the initial height hi = 0, we can rewrite the energy equation as
vf^2 = vi^2 - 2ghf = (10 m/s)^2 - 2(10 m/s^2)(5 m) = 0
Therefore, his final velocity vf is
vf = 0
Explanation:
It is given that,
Wavelength, 
Slit width, 
Order, m = 2
If the diffracted light projects onto a screen at distance 1.50 m, L = 1.5 m
For the diffraction of light,


y = 0.0037 m
So, the distance from the center of the diffraction pattern to the dark band is 0.0037 meters. Hence, this is the required solution.
The first harmonic would be the smallest frequency for a string to produce a standing wave. In addition, the strings were fixed in a single attachment and have only limited motion. It is because standing waves require a specific medium for the sound to travel in it.
