Answer:
471262.5 J
Explanation:
Total energy=Kinetic energy+ potential energy
Kinetic energy at point 3= [tex]0.5mv^{2}[/tex] where m is the mass and v is the speed
KE at point 3= [tex]0.5*250*27^{2}=91125 J[/tex]
Potential energy at point 1 and 2= mgh where g is acceleration due to gravity and h is the height
PE=mg(h1+h2)=250*9.81*(100+55)=380137.5 J
Total energy= 91125+380137.5=471262.5 J
