Question

A bus starts from rest and move with an acceleration of 50meter per sec square what distance it will cover in 30 minutes.​

Answer 1

Answer:

The distance travelled is 81000000 m.

Step-by-step explanation:

Bus starts from rest, accelerates at = 50 m/s²

Distance it will cover in 30 minutes = ??

Here:

• u = 0
• t = 30 mins = 1800 secs.
• a = 50 m/s²

$\boxed{\sf{s = ut + \frac{1}{2}a {t}^{2} }}$

$\sf{\longrightarrow} \: s = 0(1800) + \dfrac{1}{2}(50){(1800)}^{2}$

$\sf{\longrightarrow} \: s = 25 \times {(1800)}^{2}$

$\sf{\longrightarrow} \: s = 25 \times 3240000$

$\sf{\longrightarrow} \: s =81000000$

Distance travelled = 81000000 m

Therefore, the distance travelled is 81000000 m.

Answer 2

Answer:

Question :-

• A bus starts from rest and move with an acceleration of 50meter per sec square what distance it will cover in 30 minutes.

Given :-

• A bus starts from rest and move with an acceleration of 50meter per sec square.

Find :-

• What distance it will cover in 30 minutes.

Formula Used :-

${\purple{\boxed{\large{\bold{s = ut + \frac{1}{2}a{t}^{2}}}}}}$

Solution :-

We have,

• Initial velocity (u) = 0 m/s
• Time (t) = 30 mins = 1800 secs.
• Acceleration (a) = 50 m/s²

By substituting the formula we get,

$:\sf{\implies} \: s = 0 \times 1800 + \dfrac{1}{2}(50){(1800)}^{2}$

$:\sf{\implies} \: s = 25 \times {(1800)}^{2}$

$:\sf{\implies} \: s = 25 \times 3240000$

$:\sf{\implies} \: s = 81000000\: m$

Now, we have to converted m into km,

$:\sf{\implies} \dfrac{81000000}{1000}$

$:\sf{\implies} \bold{\red{81000\: km}}$

Therefore, the distance travelled is 81000 km.
