Answer to Problem 1Q

The kinetic energy of a particle with v=5i^ velocity is 5m .

Explanation of Solution

Given:

  v=5i^

Calculation:

The kinetic energy of a particle can be determined using the equation of kinetic energy.

The kinetic energy:

  KE=12mv2KE=12m522KE=12m25KE=5m

Thus, the kinetic energy of a particle with v=5i^ velocity is 5m .

(f)

To determine

To find: the kinetic energy of a particle with v=5 at 30° .

(f)

Expert Solution
Check Mark

Answer to Problem 1Q

The kinetic energy of a particle with v=5 at 30° is 5m .

Explanation of Solution

Given:

  v=5 at 30°

Calculation:

The kinetic energy of a particle can be determined using the equation of kinetic energy.

The kinetic energy:

  KE=12mv2KE=12m52cos230+sin2302KE=12m251KE=5m

Thus, the kinetic energy of a particle with v=5 at angle 30° is 5m .

Since, all particle’s kinetic energy is same.

Hence, the rating of the kinetic energy is: a=b=c=d=e=f.
