Short Answer

In , what is the maximum speed a particle could have at .

It never reach ?

Particle's maximum speed is .

See the step by step solution

Step by Step Solution

Step 1 : Speed : 

It is the change in an object's location with regard to time.

Step 2 : Explanation : 

Particle's mass ,

Formula to determine the kinetic energy of a particle ,

= kinetic energy,

= particle's mass

= particle's velocity.

Consider the graph of potential energy against distance,

The peak of the curve between .

It occurs at .

Particle's kinetic energy at must be .

It is if the particle is not allowed to reach at .

The potential energy difference of would be the particle's maximum speed so that it can never reach at .

Potential energy difference,

Particle's maximum velocity,

Hence, maximum speed of particle is .
