The graph represents the acceleration of two cars, accel 1 and accel 2, during a road trip. which statement best describes the differences between the two cars' acceleration during the trip?
a) accel 1 accelerates throughout the entire trip; accel 2 does not accelerate during the trip.
b) accel 1 rapidly accelerates and then stops; accel 2 maintains a constant velocity during the trip.
c) accel 1 has a constant rate of acceleration; accel 2 accelerates at different rates during the trip.
d) accel 1 accelerates for the first two-thirds of the trip; accel 2 has a constant rate of acceleration.

Accel 1 has a constant rate of acceleration; Accel 2 accelerates at different rates during the trip. The slope of Accel 1 remains constant; the slope of Accel 2 changes.

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.

conduct current i mean it makes sense
