A 2 meter tall astronaut standing on mars drops her glasses from her nose. how long will the astronaut have before he hits the ground?

Here,

Height (S) = 2m

Gravity on mars (g) = 3.7m/s^2

Initial velocity (u) = 0 m/s^2

By the one of the formula of the motion,

S = ut + 1/2at^2

2 = 0 * t + 1/2*3.7*t^2

2 = 1.85t^2

t^2 = 2/1.85 = 1.081

t = 1.03s

So, it will take 1.03s long ...
