The unbalanced wheel has a mass of 15 kg and rolls without slipping on the flat horizontal surface. The wheel has a radius of gyration about its mass center G of 64 mm, and its mass center is 40 mm from the center of the wheel. When the mass center G passes the horizontal line through O, the angular velocity of the wheel is 4 rad/s. For this instant, compute:
a. The angular acceleration of the wheel.
b. The normal force N and the friction force F acting on the wheel at its point of contact with the horizontal surface.
c. The minimum coefficient of friction for which the wheel does not slip.

a)

b)

c)

Step-by-step explanation:

From the question we are told that

mass of unbalanced wheel

Radius of gyration

Mass center

Angular velocity

a)

Generally the equation for moment at point A is mathematically given as

Where

b)

Generally the equation for equilibrium of system on the horizontal axis is mathematically given as

c)

Generally the equation for equilibrium of system on the vertical axis is mathematically given as

Where

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
