A bird is flying in a straight line initially at $10 m / s$ . It uniformly increases its speed to $15 m / s$ while covering a distance of 25 m . The time taken by the bird in seconds is.

Answer:

2.00

Solution:

$v^{2} = u^{2} + 2 as$

$\Rightarrow \frac{25 \times 5}{2 \times 25} = a \Rightarrow a = \frac{5}{2} m / sec^{2}$

Now $v = x + at$
