B
add them all by direction
13 East
10 West
subtract difference
3 E
Answer:
A VECTOR A IS DIRECTED ALONG THE NORTH DIRECTION ANOTHER VECTOR B IS DIRECTED IN THE SOUTH-EAST DIRECTION .THE RESULTANT CANNOT BE IN THE SAME DIRECTION
Answer:
Option C
100 J
Explanation:
Kinetic energy, KE is given by
where m is the mass and v is the velocity
Substituting 50 Kg for mass, m and 2 m/s for velocity v then we obtain
Therefore, the child's kinetic energy is equivalent to 100 J
Path 2.
Displacement is the direction and magnitude of an object from its starting point, so path 2 is the direct route you would need to take to find direction and magnitude.
The answers false I believe
