A horizontal force of 90.0 N is required to push a 75kg object along a horizontal surface at a constant speed. What is the magni

Varvara68 [4.7K]

If the object is moving at a constant speed, acceleration is 0. So:

$F = ma

F = m\times 0

F = 0$

The resultant force is 0. So the force pushing the object must be equal to the friction force acting, so

Friction = 90 N

488 J of work is done to a box which is moved across the floor for a distance of 8.9 m. What net force is required to act on the

kvv77 [185]

According to the formula
$a = f \times d$
Where a is work, f is force and d is the distance that box was moved over. And from that formula, you can get that f = a/d and that is 54.83N of force
