The momentum p of an object of mass m and velocity v is defined according to the following relationship: p=mv The velocity of any free falling object at any time is v=at
The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth. So, p=mgt=(50 kg)(9.8 m/s^2 )(2 s)=980 kg m/s
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
