How long would it take Jesse with the acceleration of -2.50 m/s to bring his bicycle with an initial velocity of 13.5 m/s to a complete stop

Time taken by Jesse to bring his bicycle =5.4 Sec

Explanation:

acceleration of bicycle = -2.5  m/sec²

Initial velocity of by cycle u =13.5 m/sec,

final velocity of bicycle v = 0 (since bicycle completely stop finally)

Let the time taken to stop the bicycle completely = t sec

We now by equation of motion,

putting the value of u,v & a in the equation

0=13.5 -2.5 x t ( a is taken as negative since velocity of bicycle is reducing)

= 5.4 Sec

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.

explanation:

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.
