A 5.4 kg shot rolls along the ground at 15 ms and collides head on with a stationary shot which has a mass of 4.0 kg. The friction force is negligible during the collision After the collision, the 4.0 kg shot moves rolls forward at 2.4 ms 'in the same direction that ttle 5.4 kg shot was initially rolling. Calculate the velocity (size and direction) of the 5.4 kg shot after the collision ​

need to see circuit to get time constant

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.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
