1. A large tank, open at the top, is filled with water to a depth of 15 m. A spout located
10.0 m above the bottom of the tank is then opened as shown in the drawing. With
what speed will water emerge from the spo
REASON FOR MOTION FORCE
GENERAL APPROACH :
Force is something that creates acceleration: F ~ a
The coefficient of proportionality between force and acceleration defines degree of inertia and is
called mass m .
Hence, F = ma
SI UNITS of force: [ F ] = [kg
By definition A = ( F r ) = F r cos = Fx rx + Fy ry + Fz rz
