Answer:

1) Her body mass is m=65.06 kg

2) Her acceleration is a= 1.99 m/s²

3) Her velocity after 2 secs is Vf= 9.98 m/s

4) She travels a distance of d= 15.98 meters in these 2 seconds.

Explanation:

W= 637.65 N

F= 130 N

vi= 6 m/s

g= 9.8 m/s²

m= W/g

m= 65.06 kg

a= F/m

a= 1.99 m/s²

Vf= Vi + a *t

Vf= 9.98 m/s

d= Vi * t + a * t²/2

d= 15.98m
