Calculating Displacement Vectors for Jasmine and Jack's Bike Rides to School

[123phy]

I need help with this question
when jasmine goes to school, she rides her bike 1.00km[e]
.70, .80[e]..50. When jack goes to school he rides his bike
.30km[w] and 1.70km (hint: start from school to home)

a)draw a scale diagram to represent all the inital displacement vectors and resultant displacement vector in their trips to school

b) what distance and do jasmine and jack travel in getting to school

Welcome to PF.

What is it you are stuck on?

the question listed above

the question listed above

And what good is my making a scale drawing again ...?

i am having trouble finding a scale for that question and drawing a scale diagram

Doesn't look like you need more that 2 km in any direction. Maybe choose .25 km per square on regular graph paper?

When Jasmine goes to school, she rides her bike 1.00 km[e], 0.70km,0.80km[e],0.50. When Jack goes to school on his skate board, he rides his skateboard 0.30km[w] and 1.70km

A) draw a scale diagram, to represent all the inital displacement vector and the resultant displacement vector in their trips to school. (Hint: start at the school and work back to their homes)

B)What distance do Jasmine and Jack travel in getting to school?
C) when jack is at school, what is his position with respect to his home?
D) if jack takes 30 min to get to his school, what is his average speed?
E)what is jacks avg velocity for his trip to school?
F) when jack is at jasmine's house what is his position with respect to his home?

I'm guessing that they are asking for both the distance and displacement for their trips?

This link might help you if you are having difficulty distinguishing between the 2.

Well, then what are your answers?

give us your answers first please so we canhave an idea if were on the right track or not?

I'm sorry. You'll have to show your work. The idea here is to help you, if you are stuck on something, not do it for you.

On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. If no attempt is made then the questioner should be asked to provide one before any assistance is given. Under no circumstances should complete solutions be provided to a questioner, whether or not an attempt has been made.

I don;t understand what kind of scale to use because o.25 cm as a skale is very confussing.

Well what scale works best for your paper? I suggested you use .25 km per square given the dimensions you are dealing with. What are the maximum dimensions you need to accommodate?
