Answer:
it takes 3 hours to travel
Explanation:
120 ÷ 40 = 3
Answer:
4N
Explanation:
Given parameters:
Weight of stone when immersed in water = 18N
Weight of water displaced = 4N
Unknown:
Weight of the stone in air = ?
Solution:
To solve this problem, we employ the Archimedes' principles.
It states that the upward buoyant force on a body is equal to the weight of the fluid displaced.
The weight of the water displaced is equal to the weight of the body.
So, the weight of the stone in air = 4N
The car's (average) acceleration would be
The car's position over time would be given by
so that after 2.4 seconds, the car will have traveled a distance of
