Answer:
You have to have gravity to be on the ground.
So what i am saying is that there is a gravitational force and magnetic force and there are so many types of gravity.
I hope thins helps.
Electric field due to a long wire is given by
here
r = 16 m
consider east-west direction along X-axis and north-south direction along Y-axis.
A = displacement along east direction = 5.5 i
B = displacement along north direction = 8 j
R = resultant displacement
Resultant displacement is given as
R = A + B
R = 5.5 i + 8 j
using Pythagorean theorem , magnitude of the resultant displacement is given as
|R| = sqrt(|A|² + |B|²) = sqrt((5.5)² + (8)²) = 9.7 blocks
By definition,
Momentum = Mass * Velocity
Let v = the velocity of the truck, m/s
The mass of the truck is 36,287 kg.
The momentum is 907,175 (kg-m)/s.
Therefore
907,175 (kg-m)/s = (36287 kg)*(v m/s)
v = 907175/36287 = 25 m/s
Answer: 25 m/s
