To Choose: The correct option.
Answer to Problem 7STP
Option A.
Explanation of Solution
Given:
Impulse on the object,
Final speed of the rock,
Formula used:
Momentum of an object of mass m and moving with velocity v is given by,
And, impulse on an object is given by the change in momentum of the object,
Calculation:
Since initially the rock was on ground, thus its initial velocity will be zero,
Using the given values in above mentioned formulas, the mass of the rock will be,
Conclusion:
Thus, the mass of the rock is
