Answer:
The answer is a. Jumper
Explanation:
The change in the momentum is represented by the equation
Acceleration of any body is calculated by the product of the mass of the body and with the velocity the same mass is moving.
Since it is mentioned in the statement that m is the mass of the jumper then velocity will also be of the jumper to calculate the change in the momentum.
If the mass of bugle cord is taken, then its velocity will be taken for the equation.
Answer: 90 kgm/s
Explanation:
The momentum (linear momentum) is given by the following equation:
Where:
is the mass of the skater
is the velocity
In this situation the skater has two values of momentum:
Initial momentum:
Final momentum:
Where:
So, if we want to calculate the difference in the magnitude of the skater's momentum, we have to write the following equation(assuming the mass of the skater remains constant):
Finally:
Resultant displacement between the base camp and the cave will be 7.211 km
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Her resultant displacement can be calculated using Pythagoras theorem
=
= 52
H = = 7.211 km
Resultant displacement between the base camp and the cave will be 7.211 km
