Answer:
Option (c) is correct. 4 s or Seconds .
Explanation:
To find : t means time taken.
Solution :
Given that,
Acceleration, a is 1.5 m/s².
Initial velocity, u is 0 m/s.
Final velocity, v is 6 m/s.
We know,
• a = (v - u)/t
Where,
a is Acceleration (in m/s²).
v is final velocity (in m/s).
u is Initial velocity (in m/s).
t is time taken (In seconds).
Put all values in formula :
\implies⟹ 1.5 = (6 - 0)/t
\implies⟹ 1.5 × t = 6
\implies⟹ t = 6/1.5
\implies⟹ t = 4
Therefore,
t (time taken) is 4 seconds .
