Answer:
Static friction
Explanation:
Static friction is the friction force that acts on objects that are not moving.
The intensity of withdrawal symptom of cocaine abuse is relative to the length of time in abuse. Symptoms also vary depending on the drug build-up to the person 's body. Some will only take the short period to recover from the abuse but other patients may take time.
Answer:
The height is 80 meters.
Explanation:
The equation for the distance in the second segment of the fall is as below. In it, we use the initial velocity v1 that the ball had after completing the first segment. From this equation, v1 can be determined:
Next, we use the kinematic equation for velocity at the end of the first segment of a free fall, to determine h1:
The total height is then
Answer:
Explanation:
