8.28 km

Explanation:  

Given

First it drifts 2.5 km

Secondly it drifts 4.70 km

After that it drifted along east direction 5.1 km

After that it drifts 7.2 km

=+

for direction

south of east

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
