Answer:
2v
Explanation:
The function of the velocity is:
v = v0 + a.t, where v is the top speed, v0 is the initial speed, a is the acceleration and t the time.
Both the tortoise and the hare start at rest, so v0 = 0. For the tortoise:
v = a.t
For the hare:
v' = a't', but a' = a and t' = 2t
v' = a*2t
v' = 2*at
v' = 2v
Answer:
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.
Explanation:
Answer:
4 cm/s².
Explanation:
From the question given above, the following data were obtained from it:
Initial velocity (u) = 0 cm/s
Final velocity (v) = 40 cm/s
Time (t) = 10 s
Acceleration (a) =?
Acceleration is simply defined as the rate of change of velocity with time. Mathematically, it is expressed as follow:
Acceleration (a) = Change in velocity /time
Acceleration (a) = [final velocity (v) – initial velocity (u)] /time (t)
a = (v – u) /t
With the above formula, we can obtain the acceleration of the ball as follow:
Initial velocity (u) = 0 cm/s
Final velocity (v) = 40 cm/s
Time (t) = 10 s
Acceleration (a) =?
a = (v – u) /t
a = (40 – 0) / 10
a = 40/10
a = 4 cm/s²
Therefore, the acceleration of the ball is 4 cm/s²
