You are in the forest with some of your friends. You’re being chased by a very angry and hungry bear. The bear can run at 8 m/s. You can run at 6 m/s. Safety is 50 meters away. How much of a head start do you need to avoid becoming bear food?

2m head start or else you done for

Explanation:

you cant even out run a bear they run at 35mph the fastest human is 25

13 yards north.

Explanation:

Distance and Displacement

A moving object constantly travels for some distance at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final points of the path defined by the object in its moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.

Coach Sweeney walks 24 yards north and 11 yards back south. If Coach Sweeney started at the origin, the first walk ends in point (0,24). After going back 11 yards, the final point is (0,13).

Since the displacement only takes the initial and final points, we can say the resultant displacement was 13 yards north.
