Barriers to physical fitness and activity may be someone's health (they may have a disease that prevents them from exercising). Other than this, there really is no limit to whom can exercise.
Hope this helps!
Answer:
2.4 m/s
Explanation:
Given:
Velocity of the object moving north = 2.1 m/s
Velocity of the river moving eastward = 1.2 m/s
The resultant velocity is the vector sum of the velocities of object and river.
Since the directions of velocity of object and river are perpendicular to each other, the magnitude of the resultant velocity is obtained using Pythagoras Theorem.
The velocities are the legs of the right angled triangle and the resultant velocity is the hypotenuse.
The magnitude of the resultant velocity (R) is given as:
Therefore, the resultant velocity has a magnitude of 2.4 m/s.
Gravity!! It also keeps the planets in orbit!

If we assume that Joe's speed is 0.6 m/s in the vertical direction, then the total displacement he must cover is 443 meters in the vertical direction. Now, the formula for average speed is:
average speed = total distance / total time
total time = total distance / average speed
total time = 443/0.6
total time = 738.3 seconds</span>
