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
