Answer:
179.655m
Explanation:
Given
Maximum speed of the arrow v = 60m/s
Time taken to hit the top of the cliff t = 7.0s
Required
Height of the cliff H
Using the equation of motion
H = vt + 1/2gt²
Substitute into the formula:
H = 60(7) + 1/2 (-9.81)(7²) (g is negative due to upward motion of the arrow)
H = 420-4.905(49)
H = 420-240.345
H = 179.655m
Hence the cliff is 179.655m high
Explanation:
This question is not feasible. There is no way to calculate the energy needed because the question is missing the final temperature
Answer:
the flywheel's average angular acceleration is -2.05 rad/s²
Explanation:
<u>Note:</u> counterclockwise is positive
clockwise is negative
Given;
initial angular velocity,
= 5.03 rev/s = 
final angular velocity,
= -2.63 rev/s = 
duration of the flywheel rotation, Δt = 23.5 s
The average acceleration of the flywheel is calculated as;

Therefore, the flywheel's average angular acceleration is -2.05 rad/s²
