Someone stuck a piece of chewing gum on the outer edge of a blade on a ceiling fan. The radius (r) of where the gum is from the center of the spinning fan is 0.60m. The period (T) that it takes for the blade to complete one revolution is 0.25seconds on its slowest speed setting. If we estimate the piece of chewed gum to have a mass (m) of 0.0026Kg, then how much centripetal Force (Fc) is on the gum when the fan is spinning at this speed?

why would u stick a gum there

Explanation:

i think it would be 80 km/h because 30 + 50 = 80 (sorry if this not the right answer i'm trying my best)

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
