Answer:
Explanation:
Velocity vs speed and distance vs displacement is a pretty important. Distance and speed have no direction while displacement and velocity have a direction.
In other words, taking the first example, going 5m one way and then 14 the other would make the total distance 19m, while displacement would be -9m from where you started.
Anyway, velocity is displacement divided by time. For the first one I already got that the displacement is -9m, and the time is 11 minutes. It's worth noting that the answers are all in m/s, so we should convert the minutes to seconds. To do that multiply 11 minutes by (60 seconds/1 minute) so the minutes cancel out. so 11*60 is 660 seconds. Now, to find velocity we just divide. -9m/660s = -.0136 Which... doesn't seem to be one of the options...
For the second part it gives two point of views. If you were standing on the carrier, the spy would look like it was moving 4 m/s away from you, but the carrier itself is moving 12 m/s in the positive direction to an onlooker. If it's hard to figure out try thinking what it would look like if the spy was just standing still. it would look like they were moving -12 m/s if you were standing on the carrier. Then if the spy was moving at say 1 m/s it would look like they were moving -11 m/s if you were standing on the carrier.
Just keep that line of reasoning , where if it looks like the spy is moving -4 m/s from the carrier then the spy is moving 4 m/s slower than the carrier, so the spy is moving at 8 m/s
Pretty sure I got the first part right, so maybe a misprint from the question?
Answer:
The displacement is 
The distance is 
Explanation:
From the question we are told that
The height from which the ball is dropped is 
The height attained at the first bounce is 
The height attained at the second bounce is 
The height attained at the third bounce is 
Note : When calculating displacement we consider the direction of motion
Generally given that upward is positive the total displacement of the ball is mathematically represented as
Here the 0 show that there was no bounce back to the point where Billy released the ball
=>
Generally the distance covered by the ball is mathematically represented as
The 2 shows that the ball traveled the height two times
=>
Answer:
a. d=1/p
Explanation:
The simple formula for calculating the distance to an object in parsecs is to divide 1 by the number of parsecs to find the distance in light years. Hope this helps!
The required initial velocity that will result if a projectile lands at the same height from which it was launched is V₀ = V cosθ
First, we must understand that the component of the velocity along the vertical is due to maximum height achieved and expressed as usin
θ.
The component of the velocity along the horizontal is due to the range of the object and is expressed as ucosθ.
If the <u>air resistance is ignored</u>, the velocity of the object will be constant throughout the flight and the initial velocity will be equal to the final velocity.
Hence the required initial velocity that will result if a projectile lands at the same height from which it was launched is V₀ = V cosθ
