If the space station is 190 m in diameter, what angular velocity would produce an "artificial gravity" of 9.80 m/s2 at the rim?

ozzi

Answer:

The angular velocity produced is 0.321 rad/s.

Explanation:

Given :

Diameter of space station , D = 190 m.

Therefore, radius , $R=\dfrac{D}{2}=\dfrac{190}{2}=95\ m.$

Also, acceleration , $a=9.8\ m/s^2.$

We know, angular velocity , $\omega=\sqrt \dfrac{a}{R}$ .

Putting value of g and R in above equation.

We get ,

$\omega=\sqrt \dfrac{9.8\ m/s^2}{95\ m}$

$\omega=0.321\ rad/s.$

Hence, this is the required solution.

Chris shoots an arrow up into the air. The height of the arrow is given by the function h(t) = - 16t2 + 64t + 23 where t is the

Ghella [55]

Completing the square gives the answer right away.

$-16t^2+64t+23=-16(t^2-4t)+23=-16(t^2-4t+4-4)+23=-16((t-2)^2-4)+23$

$\implies h(t)=-16(t-2)^2+87$

which indicates a maximum height of 87 when $t=2$ .
