Imagine an electric stove where a setting of 6 heats the coil, but it still appears black. when the dial is turned to 7, the coil begins to noticeably glow red, which means that the power density of the radiation at 700 nm (visibly red) surpassed a threshold. at what approximate temperature is the coil when it begins to glow red? assume the human eye can only perceive a glow when the power density of light reaches a minimum of 10 w/m2/μm (where y-axis units appear in the simulation in terms of megawatts (mw/m2/μ express the temperature in degrees celsius to two significant figures.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

can somebody give me the answer so i can graduate

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
