Answer:
5m/s/s
Explanation:
The units for velocity is m/s.
The units for acceleration is m/s/s
So, Determine the change in velocity and divide it by the time that change took place.
(30m/s - 10m/s)/4s = 20m/s/(4s) = 5m/s/s
Go to take picture and post it so I can see the choices for the question it will be more easy for us to answer
If you have a ream of notebook paper available, you can measure the height of the stack and divide that by the number of sheets in the ream.
Or you can look up the average density of notebook paper, measure the mass of the sheet, then find the volume by dividing its mass by its density. Then divide the volume by the length and width of the sheet.
The answer to the question is sound
Answer:
x(t) = -3sin2t
Explanation:
Given that
Spring force of, W = 720 N
Extension of the spring, s = 4 m
Attached mass to the spring, m = 45 kg
Velocity of, v = 6 m/s
The proper calculation is attached via the image below.
Final solution is x(t) = -3.sin2t
