An experiment is done to measure the acceleration of free fall of a body from rest. Which measurements are needed?
Answers
Answer:
you need the speed and the time it took in order to find the acceleration and you can find the acceleration by using this equation: A= S ÷ T where a is acceleration, s is speed and t is time.
Measurements are needed to measure the acceleration of free fall of a body from rest is the height and time of fall.
let us assume,
the body is falls from some height (h) the Initial velocity would beu = 0
The distance (h) is traveled by the body in the vertical direction with constant acceleration. the total time is taken by the body would be = tAcceleration is constant so, the equation of motion in the perpendicular direction can be applied.
That is,
[tex]y = ut + (1/2) at^2[/tex]
in this case,
y = h and a = acceleration of free fall
Solution:
Putting values in the equation:
[tex]h = 0 + (1/2) at^2\\t^2 = 2h/a \\a= 2h/t^2[/tex]
The correct answer would be the height and time of fall.

A bird flies 20 meters North, 10 meters South, and then 10 meters East. What’s the bird’s displacement? Also, can you explain how you did it? Thank you
Answers
Answer:
14.14 metres
Explanation:
Given that a bird flies 20 meters North, 10 meters South, and then 10 meters East.
the bird’s displacement can be calculated by first subtracting the value of distance from the south from the north.
20 - 10 = 10m
The displacement will be achieved by using pythagorean theorem
Displacement = sqrt ( 10^2 + 10^2 )
Displacement = sqrt( 200)
Displacement = 14.14 m
Therefore the displacement of the bird is 14.14 metres.

A wildbeest runs with an average speed of 4.0m/s for 15s . What was the distance travelled in meters
Answers
Answer:
60.0m im sorry if im wrong but this is what i got
Explanation:
Answer:
The Answer Is 60 m
Explanation:
Distance d = ?
Time t = 15 s
Average speed vavg = 4.0 m/s
You can rearrange the equation vavg = d/t to solve for distance travelled d.
vavg = d/t
d = vavgt
= (4.0 m/s) (15s)
= 60 m

Lucifer is in a train traveling initially at 5.48 m/s west when she begins to accelerate west at the rate of 0.892 m/s/s for a time of 6.90 s. What is her velocity at the end of the acceleration?

Recall that

which follows from the definition for average acceleration. So Lucifer has a final velocity of

An airplane flies with an unknown velocity due east. The plane
is experiencing wind of 12 m/s due north which produces a
resultant velocity of 35.11 m/s northeast. Determine the
unknown velocity produced by the plane engines.
Answers
Answer:
32.99m/s
Explanation:
Using the formula for calculating the resultant velocity according to Pythagoras theorem
R² = 12²+x²
35.11² = 12²+x²
X² = 35.11²-12²
X² = 1232.7121-144
X² = 1088.8121
X = √1088.8121
X = 32.99m/s
Hence the unknown velocity produced by the plane engines is 32.99m/s
The unknown velocity produced by the plane engines will be "32.99 m/s".
Given:
Resultant velocity,
R = 35.11 m/sWind speed,
12 m/sBy using the Pythagoras theorem, we get
→ [tex]R^2= 12^2+x^2[/tex]
→ [tex]35.11^2=12^2+x^2[/tex]
→ [tex]1232.712=122+x^2[/tex]
→ [tex]x^2= 1099.8121[/tex]
→ [tex]x = \sqrt{1088.8121}[/tex]
→ [tex]= 32.00 \ m/s[/tex]
Thus the answer above is right.
