Question

A 0.450kg soccer ball has a kinetic energy off 199j. Calculate the velocity of the soccer ball

Answer 1

Answer:

v = 29.73[m/s]

Explanation:

Kinetic energy is defined by the following equation:

$E_{k}=\frac{1}{2}*m*v^2 \\199=0.5*0.45}*v^2\\v=\sqrt{\frac{199}{0.5*0.45} }\\ v= 29.73[m/s]$
