Answer:
E. downward and constant
Explanation:
Freefall is a special case of motion with constant acceleration because the acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration ggg, the magnitude of velocity decreases as the ball approaches maximum height. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.
Answer:
오늘(-)중앙일보수고하셨습니다오늘하루도 화이팅입니다오늘 하루도 화이팅
Answer:
Explanation:
Given
initial angular velocity 
Time taken to stop 
using kinematic relation

here
final angualr velocity is zero because it is coming to rest
angular acceleration
thus 

Magnitude is 1283.21 rad/s
If the diameter of disk 
then
radius 
Linear acceleration is givenby 
here radial distance is
from center
thus
