Given data:
Yan speed;
Christopher speed;
Christophe starts 30 s later than Yan. Therefore, Christophe takes 30 s less than Yan to reach the same distance.
Part (A)
The distance is given as,
Let both Yan and Christophe meet at d distance from the start position. Therefore,
Substituting all known values,
Therefore, 600 s after Yan's departure Christophe will join him.
Part (B)
The distance is given as,
Substituting all known values,
Therefore, Christophe joins Yan after 6.17 km from the start.
Answer:
The center of mass of a cone is located along a line. This line is perpendicular to the base and reaches the apex. The center of mass is a distance 3/4 of the height of the cone with respect to the apex.
Explanation:
The equation to calculate the kinetic energy an object has is:
" "
Remember that M stands for the mass of the object which is the amount of weight a object has. V stands for volume which is the amount of space a object has.
Hope this helps!
