Answer:15.66 J
Explanation:
mass of block 
Force magnitude=7.5 N
Initial velocity =
Final velocity=
Initial Kinetic Energy=
=
Final Kinetic Energy=
=
Work Done =Final -Initial Kinetic energy=37.714-22.056=15.66 J
Answer:
V=483.63 m/s
Explanation:
Given that
mass ,m= 5.31 x 10⁻²⁶ kg
Kinetic energy KE= 6.21 x 10⁻²¹ J
As we know that the kinetic energy of the mass m with moving velocity V given as
Now by putting the values




V=483.63 m/s
Therefore the velocity of the molecule at the room temperature will be 483.63 m/s.
