A(n) 14 g bullet is fired into a(n) 121 g block of wood at rest on a horizontal surface and stays inside. After impact, the block slides 8.3 m before coming to rest. The acceleration of gravity is 9.8 m/s 2 . If the coefficient of friction between the surface and the block is 0.7, find the speed of the bullet before impact. Answer in units of m/s

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

i don't know that i agree with that but what's the question ?

the higher the current the higher the mag field around it the higher the influence on the compass

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.
