Deceleration = 29250 / 6500 = 4.5 m/s^2
The amount of energy needed to melt the ice is 1670 J
Explanation:
The amount of thermal energy needed to completely melt a certain amount of solid substance (already at melting point) is given by

where
m is the amount of the substance
is the specific latent heat of fusion of the substance
Here, the mass of the ice is
m = 5 g = 0.005 kg
And the specific latent heat of fusion of ice is

Assuming that the ice is already at melting point, the thermal energy needed to melt the ice is

Answer:
Explanation:
Given data:
vapor pressure P_1 = 0.6 L
Volume = 2L
Temperature remain constant
No change in vapor pressure. This is because vapor pressure is calculated from the temperature of the liquid and not the volume of the container. Since the temperature is constant therefore vapor pressure remian constant..
