Answer:
Explanation:
Given that,
Initial angular velocity, 
Final angular speed, 
Angular displacement, 
We need to find the angular acceleration of the tire. We can find it using the third equation of rotational kinematics. So,
So, the angular acceleration of the tire is equal to 
.
Answer:
we have to make another question we maxed it out again lol
Explanation:
Answer:
The acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
Explanation:
Let suppose that maximum height of the arc is so small in comparison with the radius of the Earth.
Since the ball is launched upwards, then the ball experiments a free-fall motion, that is, an uniform accelerated motion in which the element is accelerated by gravity. Then, the acceleration experimented by the motion remains constant at every instant and position.
Besides, the gravitational acceleration in the Earth and, in consequence, the acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
use the equations provided it shouldn't he hard
