Question

An object’s momentum is its mass multiplied by its velocity.  The kinetic energy of a moving object is given by the formula

KE=(1/2)mv², where m is the object’s mass and v is its velocity squared. 

 

Write two functions one for momentum and the other for kinetic energy.

The momentum function must have two required parameters and calculates/prints the object's momentum.

The kinetic energy function must have two required parameters and calculate/print the

kinetic energy.

 

Write a program that accepts an object’s mass (in kilograms) and velocity (in meters

per second) as inputs and then outputs its momentum and kinetic energy by calling the functions.

Answer 1

def Momentum ( m, v):

return( float(m)*float(v))

def KineticEnergy( m, v):

return(float(m)*float(v)*float(v))

M = input("Please input the Mass of the object :>")

V = input("Please input the Velocity of the object :>")

print(" the mass is " + str(M))

print(" the velocity is " +str(V))

print(" the momentum is " + str(Momentum(M,V)))

print(" the kinetic energy is " + str(KineticEnergy(M,V)))
