A 2.0 kg box is at rest on a table. The static friction coefficient ji, between the box and table is 0.40, and the kinetic friction coefficient pe is 0.20. Then, a 25 N horizontal force is applied to the box.
What is the best estimate of the magnitude of the box's acceleration?
Round the answer (if non-zero) to two significant digits.
Choose 1

answer :

b

explanation:

radiation warms things up temp rises convection currents air circ windy weather

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
