Answer:

Explanation:
Case 1
Given,
initial angular speed = 0 rev/s
final angular speed = 2 rev/s
time, t = 7 s
angular acceleration of the washer



using equation of rotational motion



Case 2
Given,
initial angular speed = 2 rev/s
final angular speed = 0 rev/s
time, t = 12 s
angular acceleration of the washer



using equation of rotational motion



total revolution in this case



total revolution of the washer is equal to 20 rev.
Answer:
421.83 m.
Explanation:
The following data were obtained from the question:
Height (h) = 396.9 m
Initial velocity (u) = 46.87 m/s
Horizontal distance (s) =...?
First, we shall determine the time taken for the ball to get to the ground.
This can be calculated by doing the following:
t = √(2h/g)
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) = 396.9 m
Time (t) =.?
t = √(2h/g)
t = √(2 x 396.9 / 9.8)
t = √81
t = 9 secs.
Therefore, it took 9 secs fir the ball to get to the ground.
Finally, we shall determine the horizontal distance travelled by the ball as illustrated below:
Time (t) = 9 secs.
Initial velocity (u) = 46.87 m/s
Horizontal distance (s) =...?
s = ut
s = 46.87 x 9
s = 421.83 m
Therefore, the horizontal distance travelled by the ball is 421.83 m
