A rocket fired from the earth's surface ...

A rocket fired from the earth's surface ejects `1%` of its mass at a speed of 2000 `ms^(-1)` in the first second. Find the average acceleration of the rocket in the first second.

Text Solution

Verified by Experts

For launching of rocket `(vdm)/(Dt)-mg=marArr2000((m)/(100))-mxx10=ma rArra=10ms^(-2)`
