A vector with a magnitude of 10 miles and another with 5 miles can be added to give a resultant vector of a. 0 miles b. 2 miles . 4 miles d. 16 miles e. 11 miles 3. An Olympic swimmer is crossing a 300m wide river and swimming perpendicular to the shore. Her speed in the swimming pool is 3km/hr. The river on the other hand, has a current speed of 8km/hr. a. How far downstream will she land b. How long will it take her to cross the river 4. The following vectors are given: D Please draw vector equivalent of the resulting vector when doing the following operations. A + B A - !B A +D C - D 5. Draw and calculate the magnitude of the resultant vector C = A + B B = 6N
