The formula of the kinetic energy is KE = 0.5*m*v^2.
Given m = 80 kg and KE = 4000 J,
4000 = 0.5*80*v^2
v^2 = 100
v = 10 m/s
Answer: heat to mechanical to electrical
Explanation:
Answer:
5123.79 kg
Explaination:
I did 5,123,788 divided by 1000 and got 5123.788
Then I rounded to the nearest 10th place.
Hope this helps, have a great day!
Answer:
d = 1.27m
Explanation:
Given m = 8.2×10-26kg, v = 1.1×10⁶m/s, q = +5e = 5×1.6×10‐¹⁹ C.
E = 49kN/C = 49000N/C
The displacement is given by
d = 1/2× mv²/qE = 1/2 × 8.2×10-²⁶ × (1.1×10⁶)²/(5×1.6×10-¹⁹ ×49000) = 1.27m
