An astronaut on another planet drops a 1 kg rock from rest and finds that it falls a vertical distance of 4 m in one second. On this planet, the rock has a weight of ____ N.

$4 m$

Answer:

Solution:

$s = \frac{1}{2} a t^{2} \Rightarrow 4 = \frac{1}{2} \times a \times (1)^{2}$

$a = 8$ m/s $^{2}$ ; this is the planet's surface gravity

Weight of the 1 kg rock $= ma = 1 \times 8 = 8$ N
