A diagram shows a kid 1.8 meters from a man and traveling at a velocity of 10 meters per second away from the man toward a point 11.8 meters away. For the man to save the kid by reaching him in time, the time it takes the man to travel 7 meters must equal the time it takes the kid to travel the remaining distance to the point 11.8 meters away. The question asks the reader to find the time, T, it will take the man to travel 7 meters and save the kid.

1. 1.8 m 11.8 m 7 m PROBLEM 1

2. The actual distance travelled by the kid will be = (11.8 – 1.8)m The person has to travel 7m. To save the kid, The time taken for the man to go and get the kid should be equal to the time taken by the kid to reach his arms.

3. 1.8 m 11.8 m 7 m PROBLEM 1 LOOK AT THE DIAGRAM CAREFULLY NOW!!!

4. THE KID S = 10 m A= +g = 10m/s 2 T= we got to find! U = 0m/s

5. Time taken = √2 Uniform velocity S= 7m
