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. =)
