*Let north and east as positive direction.
1. a = +30 km / 2 hr
a = +15 km/hr
2. a = +45 km / 3 hr
a = +15 km/hr
3. a = -30 km / 1.5 hr
a = -20 km/hr
4. a = -25 km / 0.5 hr
a = -50 km/hr
speed = (15+15+20+50) / 4
= 25 km/hr
velocity:
(horizontal): (+15-50)= -35 km/hr
(vertical): (+15-20)= -5km/hr
v = sqrt(35^2 + 5^2)
v = 35.36 km/hr

Coriolis effect
That’s what I remember from whenever I was in that unit.
Time taken by the rubber-soled shoes to reduce a person's potential from 3.00×10³ V to 100V is 3.91s
The initial potential difference 
is related to the final potential difference 
by
Our target is to find t, so we rearrange equation (1) for t to be
The body has a capacitance 150 pF while the foot has a capacitance 80 pF and both are in parallel connection. So, the equivalent capacitance is
The shoes of the rubber-soled has resistance 
. Plug the values for 
and C into equation (2) to get the time t.
