If a train (travelling from Albuquerque to Atlanta) is moving 33.9 meters per second when it accelerates at -2.02 m/s^2 for 1.01
maxonik [38]

Answer:

The final velocity is 31.86 m/s.

Explanation:

The final velocity can be found using the following equation:

V_{f} = V_{0} + at

Where:

V_{f} is the final velocity =?

V_{0} is the initial velocity = 33.9 m/s

a is the acceleration = -2.02 m/s²

t is the time = 1.01 s

V_{f} = V_{0} + at = 33.9 m/s + (-2.02 m/s^{2})*1.01 s = 31.86 m/s

Therefore, the final velocity is 31.86 m/s.

I hope it helps you!

How much water
nevsk [136]

Answer:

The mass is  m  =  3.75 \  kg

Explanation:

From the question we are told that

     The initial temperature is  T_1 =  15^oC

      The final  temperature is  T_2 =  100 ^o C  \ (boiling point )

Generally the maximum heat produced by  1  Liter   of  natural gas is  9000 \ cal

 So the amount of heat produced by 100 L is  

              E = 9000 * 100

=>           E = 9000 00 \  cal

Generally given that the efficiency is  \eta =  0.35

Then actual heat received by the water is

         H  =  0.35 *  E

=> H  =  0.35 *   9000 00

=> H  =  315000 \  cal

Converting to kcal  

=> H  =  315000 \  cal = \frac{315000}{1000} =  315 \ kcal

Generally the specific heat of water is  

       c_w  =  1 kcal/ kg \cdot ^oC

Generally the heat received by the water is mathematically represented as

       H  =  m *  c_w  *  (T_2 - T_1)

=>     315  =  m *  1   *  ( 100  - 15 )

=>     m  =  3.75 \  kg
