Question

necesito que me hagan este trabajo de fisica pls

Answer 1

Explicación:

calcula.

1. energía cinética:

masa = 1000 kg

velocidad = 120 m/s

$ec = \frac{1}{2} \times 1000kg \times (120( \frac{m}{s} )) {}^{2}$

$ec = \frac{14,400,000kg \frac{m {}^{2} }{s {}^{2} } }{2}$

$ec = 7200000kg \frac{m {}^{2} }{s {}^{2} }$

2

$ep = 50kg \times 12m \times 9.8 \frac{m}{s {}^{2} }$

$ep = 5880kg \frac{m {}^{2} }{s {}^{2} }$

3

$ec = \frac{1}{2} \times 1294kg \times (58 \frac{m}{s} ) {}^{2}$

$ec = \frac{4,353,016kg \frac{m {}^{2} }{s {}^{2} } }{2}$

$ec =2,176,508kg \frac{m {}^{2} }{s {}^{2} }$

4.

$ep = 143kg \times 19m \times 9.8 \frac{m}{s {}^{2} }$

$ep = 26,626.6kg \frac{m {}^{2} }{s {}^{2} }$
