The car is moving with velocity 1m/s
This is because of conservation of linear momentum.
Kinetic energy will go down accordingly (if no external force)
Answer:
v = 1.098 m/s
Explanation:
Given that,
A person walks 750m due north then 250 m due east of the entire walk takes 12 min.
We need to find the average velocity of the person.
Displacement,

Average velocity = displacement/time

So, the average velocity of the person is 1.098 m/s.
