Answer:
1185 N
Explanation:
From Newton’s second law of motion,
F=ma where m= mass of motorcycle, a is acceleration of the motorcycle and F=Force
Net force acting on motorcycle 
is given by 
Where F is force acting on motorcycle and f is frictional force
Substituting F-f for
hence ma= F- f Substituting a with 3, m with 245Kg and f with 450N as provided
245*3= F- 450
F=245*3 +450= 1185 N
Vf = Vi + at
Vf = 0 + 5.4•28
= 151.2m/s..
not sure if its right
Answer:
The current is 
Explanation:
From the question we are told that
The length of the segment is 
The current is 
The force felt is 
The distance of the second wire is 
Generally the current on the second wire is mathematically represented as
Here 
is the permeability of free space with value 
=>
