If you walk 1.4 km north and then 4.8 km east, what are the magnitude and direction of your resultant displacement?

The magnitude and direction of the resultant displacement is 5 km and 16.26° North -east.

Explanation:

Given that,

Distance in north = 1.4 km

Distance in east = 4.8 km

We need to calculate the magnitude of resultant displacement

Using formula of displacement

We need to calculate the direction

Using formula of direction

Hence, The magnitude and direction of the resultant displacement is 5 km and 16.26° North -east.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
