meed physics answer asap only need answer for 34 and 36​

Answer 1

Answer:

34) (A) 25/3

36) (B) 9.8

Explanation:

34)

$average \: acceleration \: = \frac{a1 \times t1 + a2 \times t2}{t1 + t2} \\ = \frac{5 \times 5 + 10 \times 10}{5 + 10} \\ = \frac{25}{3}$

36)

$v \: = u \: + at \\ time \: taken \: to \: reach \: maximum \: height \: be \: t \\ \: 0 = 49 - 9.8t \\ t = 5 \\ now \: 1 \: second \: before \: = 4s \\ v \: = 49 - 9.8 \times 4 \\ = 9.8$
