A jet plane makes a downward dive as shown. The bottom part of the path is a quarter circle having a radius of curvature of 350 m. At what speed (in mph) will the pilot experience an acceleration of 5.5g? Use 1 mph = 0.447 m/s. A. 125 mph
B. 620 mph
C. 1040 mph
D. 310 mph

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
