Input data

$F i n a l V e l o s i t y m = 45 K g$ $I n i t i a l D e l o s i t y v = 32 m / s$ $T i m e t = 12 s$

Solution :

$p = 1440 k g . m / s$

Formula

$s = \frac{1}{2} (v + u) t$ Where:
p = momentum
m = mass
v = velocity

Input data

$M o m m e n t u m P = 45 k g$ $V e l o s i t y v = 32 m / s$

Solution :

$m = 791.016 K g$

Formula

$m = \frac{2 K E}{v^{2}}$ Where:
PEg or PE = gravitational potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object

Input data

$M o m e n t u m P = 12 k m . m / s$ $m a s s m = 6 k g$

Solution :

$v = 2 m / s$

Formula

$v = \frac{p}{m}$ Where:
KE = kinetic energy
m = mass of a body
v = velocity of a body
