Answer:
≅ 17000 years or 1.7 x 10⁴ years
Explanation:
time= total energy/power
= (10⁸J/kg)(2x10³⁰ kg) / 3.8 x 10²⁶ J/s
= 526,315,789,473 s
= 16689 years
≅ 17000 years or 1.7 x 10⁴ years
Increase in height can cause climber's gravitational potential energy greater than any other mean
Hope this helps!
Answer:
is that rm in you profile pic
Find the acceleration:
v² - u² = 2ax
(v = final velocity, u = initial velocity, a = acceleration, x = displacement)
(82.0 m/s)² - 0² = 2 a (0.400 m)
a = (82.0 m/s)² / (2 (0.400 m))
a = 8405 m/s²
Find the time:
x = ut + 1/2 at²
(t = time)
0.400 m = 0 + 1/2 (8405 m/s²) t²
t² = (0.400 m) / (1/2 (8405 m/s²))
t = √((0.400 m) / (1/2 (8405 m/s²)))
t ≈ 0.00976 s
