Avector a with an x-component of 6.00 and a y-component of -4.40 is added to a vector b with x-component 3.30 and a y-component of -5.60. what is the magnitude of the resultant vector? use proper significant figures.

The magnitude of the resultant vector is 13.656 units.

Explanation:

The vector A can be represented vectorially as

Similarly vector B can be represented vectorially as

Thus upon adding the 2 vectors we get

Now the magnitude of the vector is given by:

|r|=

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.
