Answer:
1.05 rev/ (s)2
Explanation:
Here the disc is travelling from constant angular acceleration there for we can use motion equation for angular acceleration
(V)2 = (U)2 + 2aS
V - final angular velocity
U - initial angular velocity
S - revolution
a - angular acceleration
(15.035)2 = (10)2 + 2* a * 60
a = 1.05 rev /(s)2
Potential energy =
No, they are not both correct. Mai is correct. Water is a solution
Answer: 4 J
explanation:
The object is not at a constant speed. It is either gaining speed or losing speed.
A speed-time graph measures how fast you are going in a certain amount of time.
