Answer:
W= 38.4 J
Explanation:
Given that
m = 80 g= 0.08 kg
Initial speed ,u= 22 m/s
Final speed ,v= 38 m/s
The change in the kinetic energy of the particle
[tex]\Delta KE=\dfrac{1}{2}m(v^2-u^2)[/tex]
[tex]\Delta KE=\dfrac{1}{2}\times 0.08\times (38^2-22^2)\ J[/tex]
ΔKE= 38.4 J
We know that
Work done by all the forces =Change in the kinetic energy
That is why net work done = 38.4 J.
W= 38.4 J
Therefore the answer will be 38.4 J.
