A parachutist's fall to Earth is determined by two opposing forces. A gravitational force of 605 N acts on the parachutist. Afte
Doss [256]

Answer:15.8 m/s

Explanation:

Given

Gravitational Force F_g=605 N

Air resistance F_d=689 N

mass of Parachutist =\frac{605}{9.8}=61.73 kg

Velocity after 3 s

v=u+at

v=0+9.8\times 3

v=29.4 m/s

Now Parachutist opens the parachute

Net for on Parachutist

605-689=-84

84 N drag force

therefore deceleration \frac{84}{61.73}=1.36 m/s^2

velocity after 10 s is

v_1=v+at

v_1=29.4-1.36\times 10

v_1=15.8 m/s
