Answer:
0.42 m/s²
Explanation:
r = radius of the flywheel = 0.300 m
w₀ = initial angular speed = 0 rad/s
w = final angular speed = ?
θ = angular displacement = 60 deg = 1.05 rad
α = angular acceleration = 0.6 rad/s²
Using the equation
w² = w₀² + 2 α θ
w² = 0² + 2 (0.6) (1.05)
w = 1.12 rad/s
Tangential acceleration is given as
= r α = (0.300) (0.6) = 0.18 m/s²
Radial acceleration is given as
= r w² = (0.300) (1.12)² = 0.38 m/s²
Magnitude of resultant acceleration is given as
= 0.42 m/s²
Answer:
Which one of the following statements about sulphuric acid is correct?
Sulphuric acid is a strong oxidizing agent
Explanation:
Sulphuric acid is a very strong oxidizing agent, also it is know for its allotope of S8
The maximum velocity reached by the person is determined as 11.1 m/s.
<h3>Area under velocity - time graph</h3>
The area under the velocity time graph is the total displacement of the person.
Total Area = area of triangle formed during first 2 seconds + area of rectangle during the last 8 seconds
100 = ¹/₂(2v) + v(11 - 2)
where;
- v is the maximum velocity
100 = v + 8v
100 = 9v
v = 100/9
v = 11. 1 m/s
Thus, the maximum velocity reached by the person is determined as 11.1 m/s.
