Answer:
Explanation:
Given
initial velocity
Distance traveled before stopping
using equation of
where v=final velocity
u=initial Velocity
a=acceleration
s=displacement
v=0 as car stops after travelling
negative sign indicates it is deceleration
The angle between the two vectors is 126° 52' 11".
The given parameters;
vector A = 3.00i + 1.00j
vector B = 1.00i + 3.00j
The angle between the two vectors is calculated as follows;
The dot product of vectors A and B is calculated as;
A.B = ( 3i + 1j ) . ( 1i +3j )
= ( 3 × 1 ) + ( 1 × 3 )
= 3 + 3
= 6
The magnitude of vectors A and B is calculated as;
|A| =
|B| =
The angle between in two vectors is calculated as;
Therefore, the angle between the two vectors is 126° 52' 11".
