The particle has a mass of 0.5 kg and is confined to move along the smooth vertical slot due to the rotation of the arm oa. determine the force of the rod on the particle and the normal force of the slot on the particle when θ=30°. the rod is rotating with a constant angular velocity θ˙=2rad/s. assume the particle contacts only one side of the slot at any instant

see earlier answer

so easy. just google the electromagnetic waves and it’ll pop up.

its a 5.5 n

glad that

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
