*8â4. the winch on the truck is used to hoist the garbage bin onto the bed of the truck. if the loaded bin has a weight of 8500 lb and center of gravity at g, determine the force in the cable needed to begin the lift. the coefficients of static friction at a and b are î¼a=0.3 and î¼b=0.2, respectively. neglect the height of the support at a.

the answer is a)

answer: option c.

explanation:

v=ir = 3x15 =45 v

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.
