Hello,
Please help me solving this.
Q1-If you move 10 km North, 10 km East, and 10 km South,
a. What is your displacement? [ can not calculate it ]
b.What is the total distance you traveled? [30 km ]
2. The below graph represents the position of a mouse at a given time.

a. What is the average velocity between t = 0 to t = 4? [10 m/s]
b. What is the distance you traveled from t = 3 to t = 7? [ can not calculate it ]
c. What is the total displacement? [ can not calculate it ]
3. Answer the questions using the following graph.

a. What is the distance it traveled between t = 0 to t = 2? [20]
b. What is the instantaneous velocity when t = 4? [ can not calculate it ]
4. Jack and Michael are both running together at constant velocity of 10 m/s.
a. What is Jack's relative velocity to Michael? [10 i think ... but it's wrong]
b. What is Michael's relative velocity to Jack?
5. A rat and a cat are 25 m apart. When the rat started to run at 2 km/h, the cat started to chase him at 10 km/h. Can the cat catch the rat in 10 seconds?
YES??
so please help me to know who to calculate the [displacement-distance-relative velocity-instantaneous velocity]
i think each have a role (( equation )) but I cann't find them...
Please help..
Thank You. =)
