Calculate the force of friction that keeps an 80-kg person sitting on the edge of a horizontal rotating platform when the person
Lilit [14]

Answer:

360N

Explanation:

The frictional force = centripetal force = mass * centripetal acceleration = ma

Since centripetal acceleration = V^2/ r

Frictional force = mv^2 / r

Substitute the values of m = 80kg, radius = 2m and tangential speed = 3m/s

Frictional force = 80 * (3)^2/ 2 = 360N

how much does a bookshelf weigh if the movers are pushing it at a speed of 10 m/s^2 by applying 100 N force
Delicious77 [7]

Answer:

10 kg

Explanation:

Assuming a frictionless surface, then force F=ma where F is the applied force, m is the mass and a is acceleration. Making m the subject of the formula then m=\frac {F}{a}

Substituting 100 N for the applied force F and 10 m/s^2 for acceleration a then the value of m will be m=\frac {100}{10}=10\ kgs

Therefore, in terms of kilograms, the bookshelf weighs 10 Kg

ryan hypothesizes that darker colors heat up faster. he places a thermometer inside a red wool sock, a green cotton glove, and a
telo118 [61]
Light are transfer through waves in the atmosphere and yes it  true that the darker the color is the more heat it could absorb thus it is also explain that the lighter the color is the less heat or light its absorb its because the light is bounces back through other form of light and it lessens the amount of heat in a substance. In Ryan's procedure the possible wrong that he done is the present of a green cotton glove. Green color are one of the color that bounces light and could not support the hypothesis of Ryan and the possible temperature he could get is not the accurate one.
