A Meteorite Strikes On October 9, 1992, a 27-pound meteorite struck a car in Peekskill, NY, leaving a dent 22 cm deep in the trunk.If the meteorite struck the car with a speed of 130 m/s, what was the magnitude of its deceleration, assuming it to be constant?

Respuesta :

Answer:

Acceleration of the meteorite, [tex]a=-38409.09\ m/s^2[/tex]

Explanation:

It is given that,

A Meteorite after striking struck a car, v = 0

Initial speed of the Meteorite, u = 130 m/s

Distance covered by Meteorite, s = 22 cm = 0.22 m

We need to find the magnitude of its deceleration. It can be calculated using the third equation of motion as :

[tex]a=\dfrac{v^2-u^2}{2s}[/tex]

[tex]a=\dfrac{-(130)^2}{2\times 0.22}[/tex]

[tex]a=-38409.09\ m/s^2[/tex]

So, the deceleration of the Meteorite is [tex]-38409.09\ m/s^2[/tex]. Hence, this is the required solution.
