One way to measure g on another planet or moon by remote sensing is to measure how long it takes an object to fall a given dista

nce. A lander vehicle on a distant planet records the fact that it takes 3.17 s for a ball to fall freely 11.26 m, starting from rest. What is the acceleration due to gravity on that planet?

Answer:

2.24 m/s²

Explanation:

Using equation of motion

s = ut + \frac{1}{2}at²

u = 0 , t = 3.17 s , s = 11.26 m

Put these values in the equation above

11.26 = 0 +.5 x a( 3.17)²

a = 2.24 ms⁻².

So acceleration due to gravity on that planet will be 2.24 m s⁻².

El aspa de un ventilador de 0.30 m de diametro gira 1200 rev/min. calcule la rapidez tangencial.
Keith_Richards [23]

Answer:

v = 18.84 m/s

Explanation:

Let the question says,"The blade of a 0.30 m diameter fan rotates 1200 rev / min. calculate the tangential speed."

It is given that,

Diameter of a blade of fan is 0.3 m

Angular velocity of the fan is 1200 rev/min or 125.66 rad/s

We need to find the tangential speed of the fan. The relation is given by :

v=r\omega

r is radius of fan

v=0.15\times 125.66 \\\\v=18.84\ m/s

So, the tangential velocity is 18.84 m/s.

Two vehicles of mass M and 2M are moving in the same direction on a highway. Both drivers apply their brakes at the same time an
JulsSmile [24]

Answer:

The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2

a_{1},a_{2}=\frac{a_{1}}{2}

Explanation:

The force of friction and the kinetic force make the law of mass in moving so

F=m*a

F=f_{m}+f_{k}

f_{k1}=u*m1*g

f_{k2}=u*2*m1*g

f_{m}=\frac{1}{2}*m1*v^2

The forces are the same however at the moment to determinate the acceleration

a_{1}=\frac{F}{m}

a_{1}=\frac{F}{2*m}

\frac{F}{m} are constant because they make the same motion however the difference of mass make the acceleration difference
