Answer:
v = 0.713[m/s]
Explanation:
Kinetic energy is defined as the product of mass by the squared velocity of a body. In this way with the following expression we can have the kinetic energy as a function of velocity.
[tex]E_{kin}=0.5*m*v^{2}[/tex]
where:
m = mass = 85 [kg]
v = velocity [m/s]
Ekin = kinetic energy = 2.16*10 [J]
[tex]2.16*10 = 0.5*85*v^{2}\\v =\sqrt{0.508} \\v= 0.713[m/s][/tex]
