ok i will include both in my answer then. thank you. also should i be including the angle/direction? do you draw the s or w arrow first when drawing the diagram? like will the angle be between the hyp and 5.8 or the hyp and 6.4?

Homework Statement Tim is running cross country at 6.4m/s[S] when he completes a wide angle turn and continues at 5.8m/s[w]. What is his change in velocity? Homework Equations Δv=v2-v1 a2+b2=c2 The Attempt at a Solution i am not sure how i am supposed to find the change in...

Ok Thanks so much :)

wait...i found the angle for the velocity at the beginning and i got 65 degrees so i should probably just use the 65 degrees seeing as it was calculated with the given numbers and not my calculated rounded ones 48.6m[N65*E] ?

would my answer just be 48.6m[N66degreesE] ?

i have drawn it and using the total distance (hyp) and the upward distance (adj) i found the angle with cosine. i found 65.7 degrees as my angle

but i can't put [up(degrees)E] so how would i express that?

ok so the balloon is moving east and up relative to the ground so would i just put [E] for my direction or how would i show the fact that it is also rising?

Homework Statement A helium-filled balloon rises straight up, at a rate of 0.7m/s, for a distance of 20m before it pops. A steady breeze of 1.5m/s due east blows against the balloon. a) What is the velocity of the balloon relative to the ground? b)How long does the balloon rise before...
