Apilot can withstand an acceleration of up to 9g, which is about 88 m/s2, before blacking out. (a) what is the acceleration experienced by a pilot flying in a circle of constant radius at a constant speed of 515 m/s if the radius of the circle is 3320 m? (b) does the pilot make the turn without blacking out?

Centripetal acceleration = (speed)² / (radius)

Centripetal acceleration of our intrepid pilot = (515 m/s)² / (3,320 m)

Acceleration = (265,225 m²/s²) / (3,320 m)

Acceleration = (265,225 / 3,320) m/s²

a).  Acceleration = 79.9 m/s²

b).  79.9 m/s² is less than 88 m/s² .  So if our pilot has been taking care of himself, and has kept up with his required physical training, then he will make the turn without blacking out.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
