Answer: v = 11 m/s
Explanation:
If we ASSUME that the road is horizontal, not banked
The maximum friction force available is μmg
This will need to supply all of the required centripetal force
mv²/R = μmg
v = √(μgR) = √(0.28(9.8)(45)) = 11.1121...≈ 11 m/s
Hope this helps
Answer:In a generator, current is produced in the armature winding. Ceiling fans, cars, etc. are all examples of motor. In power stations, generator is used to generate electricity.
False: The most common salt found in ocean water would be sodium chloride. Seawater or ocean water contains many types of salt and the most abundant type of dissolved ions are sodium and chloride ions which when crystallized becomes NaCl.
Answer:
The total displacement from the starting point is 1.5 m.
Explanation:
You need to sum and substract, depending on the movement (to the right, sum; to the left, substract).
First, it moves 4.3 m right and return 1.1 m. So the new distance from the starting point is 3.2 m.
Second, it moves 6.3 m right, so the new distance is 9.5 m.
Finally it moves 8 m to the left, so 9.5 m - 8 m= 1.5 m.
Summarizing, at the end the squirrel is 1.5 m from its starting point.
Answer:
8.87 m/s^2
Explanation:
Acceleration is change in velocity over a change in time
27 to 53 = 26 m/s change in velocity
26 m/s / 3 s = 8.87 m /s^2
