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 :-
[tex] \bigstar \: \: \boxed{ \: \sf {Acceleration \: = \: \dfrac{ \: v - ᴜ \: }{ᴛ} \: }} \\ [/tex]
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 :-
[tex] \longmapsto \: \: \sf{Acceleration \: = \: \dfrac{ \: 1.8 \: - \: 1 \: }{0.03} } [/tex]
[tex] \longmapsto \: \: \sf{Acceleration \: = \: \dfrac { \: \: 0.8 \: \: }{ \: \: 0.03 \: \: } } \\ [/tex]
[tex] \longmapsto \: \: \sf{Acceleration \: = \: 26.72} \\ [/tex]
Hence :-
- Acceleration = 26.72 km/s² .
