Aparachutist weighs 1000n. when she opens her parachute, it pulls upwards on her with a force of 2000n. (a) draw a diagram to show forces acting on the parachutist. (b) calculate the resultant forces acting on the parachutist. (c) what effect will this force have on her ?

Explanation:

a) diagram is shown in attached figure.

b)

                        Resultant Force= Fnet= 2000-1000= 1000 N   (upward)

c)the force will lift parachutist  upward with acceleration  =Fnet/ m

where m is mass of parachutist    

                                                      m=weight/g

                                                          =1000/10=100 kg

               acceleration of parachutist=Fnet/ m

                                                            =1000/100

                                                      a=10 m/s²

snell's law

refractve index = sin incidence / sin refraction
