your answer is option (3) or both (1) & (2)

Answer 2

Answer:

Answer is 3. both above

Explanation:

$s \: \alpha \: {t}^{ \frac{5}{2} } \\ \\ s = k {t}^{ \frac{5}{2} } \\ \\ v = \frac{ds}{dt} = \frac{5}{2} k {t}^{ \frac{3}{2} } \\ \\ v \: \alpha \: {t}^{ \frac{3}{2} } \\ \\ a = \frac{dv}{dt} = \frac{d}{dt} ( \frac{5}{2} k {t}^{ \frac{3}{2} } ) = \frac{15}{4} k \sqrt{t} \\ \\ a \: \alpha \: \sqrt{t}$
