Se da corona sólo es eso ​

Answer 1

V = h = 10 m/s

36 \frac{km}{h} \times \frac{1000 \: m}{1 \: km} \times \frac{1 \: h}{3600 \: s} = 10 \frac{m}{s}36

Answer 2

V = h = 10 m/s

36h km×1km 1000m×3600s

1h=10smM = 40 kg

EC no sabemos cuánto vale así que Calculamos la energia cinetica

Formula : < /strong > < strong > E < /strong > < strong > c = \frac{1}{2} \times m \times {(v)}^{2}</strong><strong>E</strong><strong>c=21×m×(v)2

Entonces sustituimos los datos :
