Answer:
Explanation:
As the 2 force directions are perpendicular (North vs West), we can calculate the magnitude of the net force using the following equation
Assuming negligible friction, from here we can calculate the acceleration in accordance to Newton's 2nd law of motion
Option (A ) is correct.
Explanation:
susan is moving with constant velocity, so both the direction and magnitude of the velocity remains same. so the acceleration of susan =0. This is because an object gets accelerated when either the magnitude or direction of the speed changes.
now the force is given by
F= force
m= mass
a= acceleration
Here a =0
so F= 0
so the net force on susan is zero.
