Answer:
0.784 m
Explanation:
The motion of the ball is a projectile motion, which consists of two independent motions:
- a horizontal uniform motion, with constant speed of 
- a vertical accelerated motion, with constant acceleration 
towards the ground and initial position 
By looking at the vertical motion, we can find the time t at which the ball hits the ground, which is the time t at which the vertical position y becomes zero:
And now we can use the horizontal motion to find the total horizontal distance traveled during this time interval:
Amplitude is a measure of distance of waves
Answer: Option B
<u>Explanation:</u>
Waves are usually represented in terms of frequency and amplitude. Amplitude refers to the distance or maximum displacement traveled by the waves in terms of time which is denoted by frequency.
Frequency can be defined as the number of cycles travelled per second whereas speed is the distance travelled by the wave per second. Hence distance is the right option from the other given options.
Answer:
A goal keepee catering the ball in time is answer
The answer is B
Now I'm not sure if you're taking high school physics or middle school physics. But you have to know that gravitational potential energy has to be given with respect to something else, relative to something else.
For example if im sitting on a chair, relative to the chair my potential energy is 0, however with respect to earths core I have a huuuuuge potential energy.
So in these answers, they all have gravitational potential energy, but the answer the question is looking for is B
Answer:
Explanation:W=F*S
W=work =?
F=force =500N
S=displacement =0m
please feel free to ask if you have any questions
