A particle of mass 2×10^(−27) kg moves  according to the following  y=5cos(((πt)/3)+(π/4))  find the maximum kinetic energy
Aparticleofmass2×1027kgmovesaccordingtothefollowingy=5cos(πt3+π4)findthemaximumkineticenergy

(dy/dt)=5.sin(((Πt)/3)+(Π/4)).(Π/3)  ((dy/dt))_(max) =((5Π)/3)  k.E=(1/2).2×10^(−27) .(((5Π)/3))^2
dydt=5.sin(Πt3+Π4).Π3(dydt)max=5Π3k.E=12.2×1027.(5Π3)2

Thank you very much sir.  If I decided to compute the final  answer do I need to convert 5π/3  to degree before solving or running  it straight just like this
