Answer 1

Explanation:

Given that,

Initial Velocity = 36km/hr = 10m/s.

Acceleration = 2m/s².

Time = 1 min = 60 seconds.

We need to find,

Distance traveled.

Formula Used,

\sf {s = ut + \dfrac{1}{2} a {t}^{2} }s=ut+

Here,

s = Distance,

t = Time,

u = Initial Velocity,

a = Acceleration.

Apply the Formula.

\to \: \sf{s = 10(60) + \dfrac{1}{\cancel{2}} \times \cancel{2} \times {(60)}^{2}}→s=10(60)+

\sf{\to \: s = 600 + 60 \times 60 }→s=600+60×60→s=600+60×60→s=600+60×60

\sf{\to \: s = 600 +3600 }→s=600+3600

$\sf\implies\green{s=4200}$
