A student is whirling a stopper about her head horizontally. the mass of thr stopper id .1kg and takes 3.14 seconds to make one revolution. the radius is 2 meters. what is the stoppers speed

what is the acceleration of the stopper

what is the centripetal acceleration of the stopper

explain why it is impossible for a student to whirl the stopper completely horizontally

since the stopper didn’t spin horizontally, how does that the actual unbalanced force and radius

the answer is c.)

explanation:

i'm on my way to history not a mistory.

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.

it is b. absorbs thermal energy
