I believe this would be an example of Mary's velocity. We have her speed and direction which is all you need to find velocity.
Answer:increases
Explanation:
If we are going upward in an elevator from the ground floor to the top floor then it indicates that your distance from the center of the earth is increasing while the time period remains the same.
If the radial distance is increased then the tangential velocity of the object must be increased because the time period is the same.
This can be best explained by taking an example of a car moving in a circle of radius r. If radial is increased for the same period then the car has to travel at a higher velocity to make in time.
We can use the following equation to solve this problem:
<h3>Δp=m∣Vi−Vf∣</h3>
(Where p is the momentum change, m is mass, Vi is initial velocity, and
Vf is final velocity)
Substitute the values given to us in the question:
Δp=(0.6)∣(5.7−(−2.7)∣
Δp=4.9 kg.m/s
Final answer: 4.9kg.m/s.
The change in momentum (Δp) is defined as the change in the mass times the velocity of an object. A force is required to change the momentum of an object. This applied force can increase or decrease momentum, or even change the orientation of an object.
