Answer:
The acceleration of the fish is 0.4 m/s².
Explanation:
Fish was swimming at the speed of = 0.5 m/s
Time = 5 seconds
Fish's speed after noticing the shark = 2.5 m/s
Acceleration of the fish = ??
_____________________________
\bigstar \: {\boxed{\sf{ Acceleration = \dfrac{v - u}{t}}}}★
Acceleration=
t
v−u
v = 2.5 m/s
u = 0.5 m/s
t = 5 seconds
\sf{\longrightarrow} \: \dfrac{2.5 - 0.5}{5}⟶

2.5−0.5
\sf{\longrightarrow} \: \dfrac{2}{5}⟶

\sf{\longrightarrow} \: 0.4 \: {ms}^{ - 2}⟶0.4ms

Acceleration of the fish = 0.4 m/s²
Therefore, the acceleration of the fish is 0.4 m/s².
Answer:
Step-by-step explanation:
5/7 + (-3/8)
Taking LCM of 7 and 8 we have,
(5 x 8) / (7 x 8) + (-3 x 7) / (8 x 7)
(40/56) + (-21/56)
(40/56) - (21/56)
(40-21)/56
19/56
