A jet airliner moving initially at 366 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 127 mph in a direction 60◦ north of east. What is the new speed of the aircraft with respect to the ground?

The new speed is , in the direction   with respect to the ground

Explanation:

From the question we are told that

   The initial speed of the jet airliner is 366 mph to the east (positive x - axis )

    The direction of the wind is   toward  60° north west

     Generally the  x component of jet airliner velocity is  

      Generally the  y component of jet airliner velocity is

       Generally the  x component of winds velocity is  

        Generally the y component of winds velocity is

Generally the velocity of both the jet airliner and wind along the x-axis is

Generally the velocity of both the jet airliner and wind along the y-axis is

Generally the resultant velocity is  

=>      

=>      

 The direction is  

=>      

=>    

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
