The impulse on the rock if its velocity at the moment it strikes the ground is
Answer to Problem 9STP
Explanation of Solution
Given:
Mass of the rock,
Final speed of the rock at the moment it strikes the ground,
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 the rock falls on ground, thus its initial velocity will be zero,
Using the given values in above mentioned formulas, the Impulse on the rock will be,
Conclusion:
Thus, the impulse on the rock is
