Answer:
The answer is simple….
As we know v = u + (a×t)
Where
v is the final velocity
u is the initialvelocity
a is the acceleration
t is the time taken
So according to the question:-
u=0, v=15 , a=3 and we have to find t…
So the equation is written as:-
15 = 0 + (3×t)
=> t = (15 ÷ 3) = 5
Therefore, the time required is 5 seconds..
