Its either B. force or A. net force but I will go with force because forces can either push or pull I hope it help you.
Answer:
h = 12.6 cm
Explanation:
given,
ground reaction = 788 N
time of force application = 0.9 s
BW = 670 N
Net force = 788 - 670
= 118 N
impulse = F x t
I = 118 x 0.9
I = 107.1 N s
impulse is equal to change in momentum
v = 1.57 m/s
v is the initial velocity before jump
now, height of center of mass
using equation of motion
v² = u² - 2 g h
h = 0.1257 m
h = 12.6 cm
the height of center of mass is equal to h = 0.126 m or 12.6 cm
Answer:
t = 444.125 sec
Explanation:
Given data:
V = 24 volt
I = 0.1 ampere
mass of water mw = 51 gm
cr = 4.18 J/gm degree K^-1
mass of resistor = 8 gm
cr = 3.7 J/gm degree K^-1
we know that power is given as
Power P = VI
But P =E/t
so equating both side we have
solving for t
t = 444.125 sec
