Asmall first-aid kit is dropped by a rock climber who is descending steadily at 1.9 m/s. after 2.4 s, what is the velocity of the first-aid kit? the acceleration of gravity is 9.81 m/s 2 . answer in units of m/s.

Explanation:

From the exercise we have:

To find the velocity after 2.4s we need to use the following formula:

The negative sign means that the kit is going down.

Explanation:

All given this are:

Initial velocity is ,

Time taken,

The acceleration due to gravity is ,

So , we need to find final velocity, .

So we will use equation of motion.

. Here a is acceleration which is g .

putting all those values.

.

Hence , it is the required solution.

this means that the temperature of both substances will be equal
