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.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
