A. Material, because it's the same for each version of that element.
Answer:
The position is
Explanation:
The kinetic energy of the motion is
So apply the conservation of energy the force of the spring is the same of the kinetic energy
Solve to do
The strong man cant hold a weight on a chain completely straight due to the gravity and the mass of the chain/chair,
<span>Acceleration due to gravity at surface radius = approx 23 (m/s)/s</span>
... We know that there are no forward or backward forces on the object, because its forward speed is constant.
... The left and right forces on the object add up to zero, so it won't begin to move left or right. It'll just keep on with the same 20 m/s forward motion.
... Its velocity after 2 seconds, 10 seconds, or an hour, will still be 20 m/s forward.
Answer:
A vector is any quantity with both magnitude and direction. Other examples of vectors include a velocity of 90 km/h east and a force of 500 newtons straight down.
