Calculate kinetic friction (in newtons rounded to nearest tenth) on a 40kg crate being pulled by a rope with a tension of 141N at an angle of 30 degrees from horizontal. The crate is initially moving right but slows down at a rate of 1.5m/s^2

iron would move it is magnetic there is a mag field around the current in the wire

measure their densities same density, same sub

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.
