A 30 kg object has a frictional force of 60 N. It's coefficient of friction must be...?

Physics
1 answer:
MrRa [10]3 years ago
3 0

mass = 30kg

frictional force = coefficient of friction * (mass * g)

g = 9.8 m/s^2

So:

60N = x * 294 N

x = 60 N / 294 N = 0,2

How could I tell if an egg is hard boiled or raw explain using Newton's law of motion
Thepotemich [5.8K]

Answer:

Explanation:

Newton's 2 nd law of motion tells that when equal torque is applied on object having higher moment of inertia , it will rotate slower .

Moment of inertia of boiled egg is higher because the whole egg rotates as s solid unit . Hence it will rotate slower or it rolls slower on an inclined surface .

In this way by applying Newton's law , we can identify raw or boiled egg .
