Answer:
0.176m from the flagpole, westward.
Explanation:
Let the Eastward be the positive direction. So initially runner A is at position -6km, running with velocity of 9km/h while runner B is at position 5km running at a velocity of -8km/h. We can conduct the following equation for their distances over the same time t
When A an B meets, they are at the same position and at the same time. So
So where they meet is 0.176m from the flagpole, westward.
The block's velocity is determined as 10.03 m/s.
<u>Explanation:</u>
According to work energy theorem, the work done on an object is equal to the change in kinetic energy of the object.
So, work done = Kinetic energy
Thus, the velocity can be determined as
Velocity = 10.03 m/s.
So the block's velocity is determined as 10.03 m/s.
