Question

A skydiver falls with an acceleration of 9.8m/s2, and reaches terminal velocity after 1.5 minutes. If their initial velocity was 0m/s, calculate their trminal velocity

Answer 1

Explanation:

it is a free fall case where a=g

neglecting the air resistance use first equation of kinematics;

v=u+at

where a=9.8m/ s^2

t=1.5min=1.5*60=90sec

u=0

so, v=0+9.8*90

=882m/s
