Problem 4: A jet airliner movin
102 mi/h in a
nitiaily at 3.00 x 102 mi/h due east enters a region where the wind is blowing 1.00 x
30 0° north of east.
a)
Find th components of the velocity of the jet airliner relative to the air, VA
b) Find the components of the velocity of the air relative to Earth,
c)write an equation relating the velocities
d)What are the speed and direction of the aircraft relative to the ground?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
