What constant horizontal force is required to drag a 5 kg block along a
horizontal surface with an acceleration of 1 ms-2 if the coefficient of
sliding friction between the block and the surface is 0.5. ​

Answer:

25N

Explanation:

formula=> Frictional force= coefficient of friction x normal reaction

normal reaction is mass x gravity(10N/kg)

so Frictional force= 0.5x5x10

=25N

but that is the Frictional force not the constant force

to get the constant force, subtract the Frictional force from the weight of the block

weight= mass x gravity

= 5x10

= 50N

50N-25N

=25N
