VECTORS HELP

A photo of MariamGuled MariamGuled
sam walks in 0.5 hours at 5 km/hour and then runs for 0.5 hours at a rate of 8km/h. if the two directions were not parallel is it possible for the resultant vector to have a value of 12km/h? EXPLAIN BRIEFLY



kyle is flying his airplan at 180km/h when he encounters a wind at 90 degrees to his direction of motion. How will the ground velocity of his airplane be affected as a result?



im having trouble with these two questions.. any help is appreciated!

not sure if i understand the question correctly but if it's asking whether a 5km/hr vector plus an 8km/hr vector can make a 12km/h vector then yes since 5+8>12. but if it's asking whether 2.5km + 4km can somehow make 12km then no.

the magnitude of the velocity of his airplane will increase. it'll also point to a slightly altered direction to the heading the plane is currently on. (max 90degree difference)
