Question

3. final velocity = 25, initial velocity = 15, average velocity = ?

Answer 1

v = 20 m/s

Step-by-step explanation:

Answer 2

`\dashrightarrow \: { \tt{average \: velocity = (v + u)/(2) }} \\`

• u is initial velocity

• v is final velocity

`\dashrightarrow \: { \tt{average \: velocity = (25 + 15)/(2) }} \\ \\ = { \tt{ (40)/(2) }} \\ \\ = { \tt{20 \: m {s}^( - 1) }}`
