Answer:
d) Both a and b are correct
Explanation:
Displacement: It is defined as the distance between initial and final position during motion.
Distance: It is defined as the total path length traveled by object
Or
It is the distance of one place from other place.
Student said that the displacement between my dorm and the lecture hall is 1km.
It is not displacement .It is distance or we say path length.
Therefore, he is using incorrect physical quantity for the information provided.
He should have called distance 1 km or path length 1 km.
Option d is true.
Answer:
b. it has the same centripetal acceleration as car A.
Explanation:
According to the question, the data provided is as follows
Constant speed of car A = 20 m/s
Constant tangential acceleration until its speed is 40 m/s
Based on the above information, the true statement is the same centripetal acceleration as car A because
As we know that
Centripetal acceleration is
where,
= velocity
r = radius of the path
Now if both car A and car B moving in the same or identical circular path having the same velocity so in this case there is the same centripetal acceleration for that particular time
hence, the second option is correct
