The average act on her during the deceleration is 4.47 meters per second.
Step-by-step explanation:
Given:
youngster mass m = 50.0 kg
She steps off a 1.00 m high platform that is s = 1 meter
She comes to rest in the 10-meter second
To Find:
The average force and momentum
Formulas:
p = m * v
F * Δ t = Δ p
vf^2= vi^2+2as
Solution:
a = 9.8 m/s
vi = 0
vf^2= 0+2(9.8)(1)
vf^2 = 19.6
vf = 4.47 m/s .
Therefore the average force is 4.47 m/s.
