In a vertical dive, a peregrine falcon can accelerate at 0.6 times the free-fall acceleration g (that is, at 0.6 g ) in reaching a speed of about 113 m / s. If a falcon pulls out of a dive into a circular arc at this speed and can sustain a radial acceleration of 0.6 g , what is the radius R of the turn?

2171.6 m

Explanation:

Given

Peregrine falcon dives in circular arc with radial acceleration of

falcon achieves a velocity of

Radial acceleration is the acceleration towards the center and it depends upon speed and radius of arc

answer; the correct answer is technician a; ///100%good luck

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
