An object is dropped from rest from a height 5.6 × 106 m above the surface of the earth. If there is no air resistance, what is

marshall27 [118]

Answer:

The answer to your question is: 10.48 km/s

Explanation:

Data

h = 5.6 x 10⁶ m

g = 9.8 m/s²

Formula

vf = $\sqrt{2gh}$

Substitution

vf = $\sqrt{2(5.6 x 10^{6}) (9.81)}$

vf = $\sqrt{109760000}$

vf = 10476.64 m/s

convert to km/s

vf = 10476.64/1000

vf = 10.48 km/s

A(n) 69.8 kg astronaut becomes separated from the shuttle, while on a space walk. She finds herself 60.4 m away from the shuttle

alukav5142 [94]

Answer:

The time taken is 6.7 min

Explanation:

Using the linear momentum conservation theorem, we have:

$m_1*v_{o1}+m_2*v_{o2}=m_1*v_{f1}+m_2*v_{f2}$

when she was 60.4m from the shuttle, she has zero speed, so the initial velocity is zero.

$m_1*0+m_2*0=m_1*v_{f1}+m_2*v_{f2}\\m_1*_{f1}=-m_2*v_{f2}\\v_{f1}=-\frac{m_2*v_{f2}}{m_1}\\\\v_{f1}=-\frac{0.886kg*12m/s}{69.8kg}\\\\V_{f1}=-0.15m/s$

That is 0.15m/s in the opposite direction of the camera.

the time taken to get to the shuttle is given by:

$t=\frac{d}{v_{f1}}\\\\t=\frac{60.4m}{0.15m/s}\\\\t=403s\\t_{min}=403s*\frac{1min}{60s}=6.7min$

Why will a sheet of paper fall slower than one that is crumbled into a ball

It’s coming in contact with more air molecules than I would if it was in a ball because there is less surface area
