Velocity = distance /time
acceleration = velocity / time
Answer:
Explanation:
We know that speed is defined as distance moved per unit time hence expressed as 
where v is speed in m/s, d is distance in m and t is time in seconds. Making d the subject of the above formula then
Substituting 343 m/s for d and 10 s for t then
Therefore, the distance between speaker and deter is

Answer:
6 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 4 m/s
Acceleration (a) = 2 m/s²
Distance (s) = 5 m
Final velocity (v) =?
The final velocity of the object can obtained as shown below:
v² = u² + 2as
v² = 4² + (2 × 2 × 5)
v² = 16 + 20
v² = 36
Take the square root of both side.
v = √36
v = 6 m/s
Therefore, the final speed of the object is 6 m/s.
