Question

A meteoroid changed velocity from 1. 0 km/s to 1. 8 km/s in 0. 03 seconds. What is the acceleration of the meteoroid?.

Answer 1

• Initial velocity=1km/s=u
• Final velocity=1.8km/s=v
• Time=t=0.03s

Acceleration be a

`\\ \rm\Rrightarrow a=(v-u)/(t)`

`\\ \rm\Rrightarrow a=(1.8-1)/(0.03)`

`\\ \rm\Rrightarrow a=0.8/0.03`

`\\ \rm\Rrightarrow a=26.67km/s^2`

Answer 2

Question :-

• A Meteoroid changed Velocity from 1.0 km/s to 1.8 km/s in 0.03 sec . What is the Acceleration of the Meteoroid ?

Answer :-

• Acceleration of the Meteoroid is 26.72 km/s² .

Given :-

• Initial Velocity = 1 km/s
• Final Velocity = 1.8 km/s
• Time = 0.03 seconds

To Find :-

• Acceleration = ?

Solution :-

As per the provided information in the given question, we have been given that the Initial Velocity of the Meteoroid is 1 km/s . Its Final Velocity is given 1.8 km/s . Time is given as 0.03 seconds . And, we have been asked to calculate the Acceleration of the Meteoroid .

For calculating the Acceleration , we will use the Formula :-

`\bigstar \: \: \boxed{ \: \sf {Acceleration \: = \: ( \: v - ᴜ \: )/(ᴛ) \: }} \\`

Where ,

• v denotes to the Final Velocity
• ᴜ denotes to the Initial Velocity
• ᴛ denotes to the Time

Therefore , by Substituting the given values in the above Formula :-

`\longmapsto \: \: \sf{Acceleration \: = \: ( \: 1.8 \: - \: 1 \: )/(0.03) }`

`\longmapsto \: \: \sf{Acceleration \: = \: \frac { \: \: 0.8 \: \: }{ \: \: 0.03 \: \: } } \\`

`\longmapsto \: \: \sf{Acceleration \: = \: 26.72} \\`

Hence :-

• Acceleration = 26.72 km/s² .
