Question 8
Two cars A and B at rest took off from a spot towards
a town. Car A was the first to take off at 2ms 2. Car B
took off 5s later and travelled at 3.4ms.
(a) Calculate when the two cars met.
(6) Find where the two cars mct.
(c) What are the velocities of the cars when they met.

overcharge is the right answer system

i don't understand. explain it clearly

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.
