John walks 1.00 km north, then turns right and walks 1.00 km east. his speed is 1.50 m/s during the entire stroll. a) what is the magnitude of his displacement, from beginning to end? b) if jane starts at the same time and place as john, but walks in a straight line to the endpoint of john's stroll, at what speed should she walk to arrive at the endpoint just when john does?

Ireally don’t know

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
