Answer 2

$\large \tt \: formula : \\ \\ \large \tt \: \:a = \frac{v - u}{t} \\ \\ \large \rm \: where \\ \\ \large \tt\: a = accelration \\ \\ \: \large \tt \: v = final \: \: velocity \\ \\ \large \tt \: u = initial \: \: velocity \\ \\ \large \tt \: t = time \: \: taken$

Here,

$\:$

• Initial Velocity = 20cm/s

• Final Velocity = 80cm/s

• time = 40s

$\:$

$\large \tt : \implies \: a = \dfrac{80 - 20}{4 0 } \\ \\ \\ \large \tt : \implies \: a = \dfrac{60}{4 0 } \\ \\ \\ \large \tt : \implies \: a = \dfrac{6 \cancel0}{4 \cancel0 } \\ \\ \\ \large \tt : \implies \: a = \dfrac{ \cancel6 \: \: 3}{ \cancel4 \: \: 2} \\ \\ \\ \large \tt : \implies \: a = \dfrac{3}{2 }$

maximum Acceleration = 3/2 = 1.5 cm/s
