Answer:
4 m/s
Step-by-step explanation:
A bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5 m/s^2 for 3 s. After the wind stops, the bird is flying to the right with a velocity of 2.5 m/s.
Assuming the acceleration from the wind is constant, what was the initial velocity of the bird before the gust of wind?
Let say Initial Velocity of Bird = U m/s
Final Velocity of Bird V = 2.5 m/s
acceleration a = -0.5 m/s² ( as opposite to the fly direction)
Time T= 3 sec
Applying formula
V = U + aT
=> 2.5 = U + (-0.5)3
=> 2.5 = U -1.5
=> U = 4 m/s
the initial velocity of the bird before the gust of wind = 4 m/s
Answer:
The probability that the proportion of flops in a sample of 442 released films would differ from the population proportion by greater than 4% is:
= 0.094
= 9.4%
Step-by-step Explanation:
Estimated probability that the films released are flops = 9%
Sample of released films = 442
Estimated number of flops = 39.78 (442 * 9%)
If the population proportion of flops will be greater by 4%,
Therefore, the number of flops will increase to 41.37 (39.78 * 1.04)
This gives a new proportion of flops as 0.0936 (41.37/442)
Answer:
1) 250 meters= 0.25 km
2) 12 meters= 0.012km
3) 1 meter= 0.001 km
The constant of proportionality is 1000 meters in 1km (1000 meters)
I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!
