Question 27 1 pts
Jonah places a 9.05 kg box on a 21° ramp. The box accelerates at a rate of 0.44 m/s2. What is the
coefficient of kinetic friction between the box and the ramp?
a. 0.21
b. 0.41
c. 0.34
d. 0.54

which three statements are true about all alloys?

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.
