For this question we should apply
a = v^2 - u^2 by t
a = 69 - 0 by 4.5
a = 69 by 4.5
a = 15.33
a = 6.85 m/s^2
If the answer in option is near to answer then , you can mark it as correct.
.:. The acceleration is 6.9 m/s^2

Answer:
east of south
Explanation:
Given:
- distance of the person form the initial position,
- direction of the person from the initial position,
north of east
- distance supposed to travel form the initial position,
- direction supposed to travel from the initial position, due North
<u>Now refer the schematic for visualization of situation:</u>
...............(1)
.................(2)
<u>Now the direction of the desired position with respect to south:</u>
east of south
<u>Now the distance from the current position to the desired position:</u>
Answer:
887.1Hz
Explanation:
Given parameters:
Speed of sound wave = 330m/s
Wavelength = 0.372m
Unknown:
Frequency = ?
Solution:
To solve this problem, we use the expression below:
Speed = Frequency x wavelength
330 = Frequency x 0.372
Frequency = 887.1Hz
Answer:
hi, this is the answer
Explanation:
A horizontal line on a distance-time graph shows no change in distance, therefore there is no motion.
The object is stationary. ...
Constant speed is motion that occurs with the same ratio of distance to time throughout the entire length of the motion.
pls mark this as the brainliest...
