Given
initially steam is at and converted to
ice
Let m be the mass of steam
latent heat of fusion and vaporization for water is
Heat required to convert steam in to water at
Heat required to lower water temperature to
Heat required to convert water to ice at
is
So this energy is equal to kinetic energy of bullet of mass m moving with velocity v
Answer:
18.7 m
Explanation:
= initial speed of the shot = 13 m/s
θ = angle of launch from the horizontal = 47 deg
Consider the motion along the vertical direction
= initial velocity along vertical direction = 13 Sin47 = 9.5 m/s
= acceleration along the vertical direction = - 9.8 m/s²
y = vertical displacement = - 1.80 m
t = time of travel
Using the kinematics equation
- 1.80 = (9.5) t + (0.5) (- 9.8) t²
t = 2.11 s
Consider the motion along the horizontal direction
x = horizontal displacement of the shot
= initial velocity along horizontal direction = 13 Cos47 = 8.87 m/s
= acceleration along the horizontal direction = 0 m/s²
t = time of travel = 2.11 s
Using the kinematics equation
x = (8.87) (2.11) + (0.5) (0) (2.11)²
x = 18.7 m
