Two cars are heading towards one another . car a is moving with an acceleration of 11. and carb is moving at -4 m/s^2. the cars are at rest and seperated witha distance of s=1400m. what time do the cars meet?

13.7 s

Explanation:

The position at time t of car A can be written as follows:

where

is the acceleration of car A

The position of car B instead can be written as

where

is the acceleration of car B

d = 1400 m is the initial separation between the cars

The two cars meet when

Using the two equations above,

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
