Question

3. An airplane taking off increases its velocity from 10.0 m/s to 100.0 m/s in 2.0 s. What is the

acceleration of the plane at this point?

Answer 1

`\huge\boxed{ \mathcal{ \purple{Solution :}}}`

we know,

`\boxed{a = (v - u)/(t) }`

where,

• a = acceleration
• v = final velocity
• u = initial velocity
• t = time

so,

`\longmapsto{a = (100 - 10)/(2) }`

`\longmapsto{a = (90)/(2) }`

`\longmapsto{ \boxed{ \mathfrak{ a = 45 \: ms {}^( - 2) }}}`

Acceleration = 45m/s²
