The boy weighs 50.0 kg when he is 1R from the center of the Earth. To get his weight  5R away, we can use the formula:

W_{boy} = G * m1 * m2 / r^{2}

Where G, m1, and m2 are constants. By ratio and proportion:

W_{boy}  * ((5R)^{2}= 50.0 kg * 9.81 m/ * ((1R)^{2}

Canceling R on both sides and by computation:

W_{boy}= 19.6 N

A 1.3-kg model airplane flies in a circular path on the end of a 23-m line. The plane makes
storchak [24]

(a) The plane makes 4.3 revolutions per minute, so it makes a single revolution in

(1 min) / (4.3 rev) ≈ 0.2326 min ≈ 13.95 s ≈ 14 s

(b) The plane completes 1 revolution in about 14 s, so that in this time it travels a distance equal to the circumference of the path:

(2<em>π</em> (23 m)) / (14 s) ≈ 10.3568 m/s ≈ 10 m/s

(c) The plane accelerates toward the center of the path with magnitude

<em>a</em> = (10 m/s)² / (23 m) ≈ 4.6636 m/s² ≈ 4.7 m/s²

(d) By Newton's second law, the tension in the line is

<em>F</em> = (1.3 kg) (4.7 m/s²) ≈ 6.0627 N ≈ 6.1 N
