# Initilization of variables
m=600 # kg # mass of the roller
r=0.25 # m # radius of the roller
P=850 # N # Force
v=3 # m/s # velocity to be acquired
theta=30 # degree # angle made by v with the force P
# Calculations
# The distance required to be rolled is given by equating the Work done between positions 1 & 2 as,
x=((0.75)*m*v**2)/(P*cos(theta*(pi/180))) # m
# Results
print"The distance required to be rolled is ",round(x,1),"m"
The distance required to be rolled is 5.5 m
