$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Acceleration=0.0834\:m/s^{2}}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{Given :}} \\ \tt: \implies Initial\:velocity(u) =10 \: m/{s}\\ \\ \tt: \implies Final \: velocity(v) = 15 \: m/s\\\\ \tt:\implies Time(t)=60\:sec \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Acceleration(a) = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies v = u + at \\ \\ \tt: \implies 15 = 10 + a \times 60 \\ \\ \tt: \implies 15 - 10 = a \times 60 \\ \\ \tt: \implies 5 = a \times 60 \\ \\ \tt: \implies a = \frac{5}{60} \\ \\ \green{\tt: \implies a = 0.0834 \: {m/s}^{2} } \\ \\ \blue{ \bold{some \: related \: formula}} \\ \orange {\tt \circ \: {v}^{2} = {u}^{2} + 2as} \\ \\ \orange {\tt \circ \: s= u t + \frac{1}{2} {at}^{2} }$

CORRECT QUESTION -

Velocity of a particle increases from 10 m/s to 15 m/s in 5 Seconds.

What will be its acceleration after a time interval of 1 minuite ?

1. 3.33 metre per second sq.

2. 33.3 metre per second sq.

3. 0.03 metre per second sq.

4. 3 metre per second sq.

SOLUTION -

In the above Question, we have the following information....

Velocity of a particle increases from 10 m/s to 15 m/s in 5 Seconds.

Here, the initial velocity of the Particle is 10 m / s

We know that :

1 minuite = 60 seconds.

So,

According to Newton ' s first law of motion -

A = { V - U } / t

Where :

V is the final Velocity.

U is the innitial velocity.

t is the time period.

Here,

Acceleration = { 15 - 10 } / 60 ={ 1/ 12} m / s ^ 2. = 0.0834 m / s ^ 2.

So the acceleration of the body after 1 minuite becomes 0.00834 m / s ^ 2.

None of the given options are correct.

ANSWER :

THE acceleration of the body after 1 minuite becomes 0.00834 m / s ^ 2.
