Answer:
The support force/ Normal reaction force
Explanation:
Refer to Newtons third law.
"The third law states that when a force acts on a body due to another body, then an equal and opposite force acts simultaneously on that body"
Since we have a downward force acting on your object, in this case gravity/weight, there is an equal and opposite force given off by the surface the object is on. This is called the support force or the normal reaction force
Runner 2 sees Runner 1 passing him with a velocity of 17 m/s west.
My guess would be 101 kPa but I'm not 100% sure, sorry.
