Question

400 meters
the total path length traveled from point k to l (demonstrated with blue line ) is 700 m. a cat travels from point k to l in 100 seconds.
q.10. what is the cat’s distance?
a) 400 meters b) 700 meters
c) 400 meters to the east d) 700 meters to the east
q.11. what is the cat’s displacement?
a) 400 meters b) 700 meters
c) 400 meters to the east d) 700 meters to the east
q.12. what is the speed of the cat?
a) 4 m/s b) 7 m/s
c) 4 m/s to the east d) 7 m/s to the east
q.13. what is the velocity of the cat?
a) 4 m/s b) 7 m/s
c) 4 m/s to the east d) 7 m/s to the east

Explanation:

Step1: Define distance

Distance is the total path length traveled. Given the cat travels a total path length of 700 m from K to L.

Step2: Define displacement

Displacement is the straight - line distance from the initial to the final position. Here, the straight - line distance from K to L is 400 m and assume the direction is to the East.

Step3: Calculate speed

Speed is calculated as $speed=\frac{distance}{time}$. Given distance = 700 m and time = 100 s, so $speed=\frac{700}{100}=7$ m/s. Speed is a scalar quantity and has no direction.

Step4: Calculate velocity

Velocity is calculated as $velocity=\frac{displacement}{time}$. Displacement = 400 m (to the East) and time = 100 s, so $velocity=\frac{400}{100}=4$ m/s to the East. Velocity is a vector quantity and has a direction.

Answer:

Q.10. b) 700 meters
Q.11. c) 400 meters to the East
Q.12. b) 7 m/s
Q.13. c) 4 m/s to the East
