Answer:
Value of magnitude of acceleration will be
Explanation:
It is given that when a stone is dropped it takes 2.2 sec to reach the ground
(a) As the stone is dropped from the top of building
So its initial velocity will be 0 m /sec
(b) As the stone is free falling and there is no external force applied on it so its acceleration will be equal to acceleration due to gravity
So value of magnitude of acceleration will be equal to

Answer:
Momentum, p = 7.2 g-m/s
Explanation:
It is given that,
The momentum of an object is
We need to express momentum in any equivalent units. There can be many solutions of this problem. Some of the units of mass are gram, milligram etc. units of length are meters, mm etc.
Since, 1 kg = 1000 gram
So,
Therefore, the momentum of the object is 7.2 g-m/s. Hence, this is the required solution.
