What is the kinetic energy of a 50-kg child running to catch the school bus at 2 m/s
aev [14]

Answer:

100 J

Step-by-step explanation:

The formula for kinetic energy is as follows:

\boxed{KE=  \frac{1}{2} mv²}

where

KE= kinetic energy (J)

m= mass (kg)

v= velocity (m/s)

Given: m= 50 kg, v= 2 m/s

Substituting the given information into the formula:

KE

= ½(50)(2²)

= ½(50)(4)

= 100 J

Solve quadratic equation 10x^2+x-2=0
zhuklara [117]

Answer:

\{-\frac{1}{2} \} \cup \{\frac{2}{5}\}

Step-by-step explanation:

10x^2 + x - 2 = 0; \\ a = 10, b = 1, c = -2; \\ D = b^2 - 4ac = 1^2 - 4 * 10 * (-2) = 1 + 80 = 81 = 9^2, > 0; \\ x_{1, 2} = \frac{-b \pm \sqrt{D}}{2a} = \frac{-1 \pm \sqrt{9^2}}{2 * 10} = \frac{-1 \pm 9}{20} = \left \ [ {{\frac{-1 - 9}{20} = -\frac{10}{20} = -\frac{1}{2}  } \atop {\frac{-1 + 9}{20} = \frac{8}{20} = \frac{2}{5}}} \right.
