Question 8

An atmospheric research probe is descending vertically. After deploying its drogue parachute, the probe's speed decreases from 84 m/s to 36 m/s.

During this braking phase, the probe experiences a constant deceleration of magnitude 8.0 m/s2.

Calculate the vertical distance, sss, the probe descends during this braking phase.

Use the equation:

v2−u2=2as v^2 - u^2 = 2as v2−u2=2as
