Answer:
Therefore, both balls will hit the ground at the same distance from their respective starting points and at the same time.
Explanation:
Both balls will hit the ground at the same distance and at the same time assuming they both start at the same initial elevation from the ground.
We know that range in the projectile motion given as

sin 60° = sin 120° =0.866
Therefore, the maximum range will be identical assuming both golfers hit the ball at the same elevation from the ground.
As for the time...
Where v is 0 m/s (final velocity at highest point), v0 is the initial velocity (for both golfers) and is the acceleration due to gravity (-9.8 m/s^²). As you can see, the time it takes to get to the highest point is independent of the angle; it is only dependent on the initial velocity. Since both golfers hit the ball with the same speed, the time for the ball to reach the highest point will be the same. Also, since it's a parabola, you can multiply the time by 2 for each golfer to get the time it takes to hit the ground.
Therefore, both balls will hit the ground at the same distance from their respective starting points and at the same time.
Answer:
what is the question?
Explanation:
I'm not sure if this was a question because you gave the answer lol
Answer:
0m/s²
Explanation:
A body with a constant speed always has a zero acceleration
Hence if Korey ran around the track at 10 meters per second and had a constant speed and did not change directions, then his acceleration will be 0m/s² not considering his initial speed
Answer:
f =63.64Hz
Explanation:
The equation of the transverse periodic wave
y = 0.005 sin(20.0x + 2ft)
From the equation we can deduce that
Amplitude A = 0.005
Wave number K = 20
Angular frequency w = 2πf
We are asked to find the frequency (f)
the formular for the wave number is given as K = 2π / lambda
Lambda = 2π/ K
Lamda is the wavelength
= 2 × 3.142 /20
= 0.3142m
The velocity of the wave is expressed as v = frequency × lamba (wavelength)
Frequency = velocity / wavelength
f = 20/ 0.3142
f = 63.65Hz
Option (C) is the correct one.
Explanation:
Coulmbs law here is,

Which is almost equal to optionC.
