Answer:
#Where is in meters and in seconds.
Explanation:
Given that :
From we have:
From we have that:
Now,given that the initial value problem is given by:
Hence,the position of u at time t is given by
, in meters, in seconds.
Hi, this is a question about an experiment, video or lesson you did in class so just look at what you predicted would happen and if it happen then your answer is yes,<span> the aluminum foil and the versoriums </span>did react the way I predicted, but if not then just say no it did not and say how you can improve your predictions
Answer:
2.47 s
Explanation:
Convert the final velocity to m/s.
We have the acceleration of the gazelle, 4.5 m/s².
We can assume the gazelle starts at an initial velocity of 0 m/s in order to determine how much time it requires to reach a final velocity of 11.1111 m/s.
We want to find the time t.
Find the constant acceleration equation that contains all four of these variables.
Substitute the known values into the equation.
- 11.1111 = 0 + (4.5)t
- 11.1111 = 4.5t
- t = 2.469133333
The Thompson's gazelle requires a time of 2.47 s to reach a speed of 40 km/h (11.1111 m/s).
138.176cm is how much it equals to
