You are on a parkour course. first you climb a angled wall up 9.5 meters. they you shimmy along the edge of a 3.5 meter long wall. lastly you traverse 15 meters of obstacles to reach the end of the course. the trip takes 43 seconds. what is your average speed? question 8 options: 0.65 m/s 1204 m/s 1.5 m/s 0.22 m/s

The average speed would be  0.65 m/s, therefore the correct option is (A).

The average speed is calculated by the formula

Average speed= (total distance/ total time)

The total distance of the trip=9.5+3.5+15=28 m

The total time of trip=43 sec

Therefore the average speed=28/43=0.65 m/s.

im not to sure what it is

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
