Force = mass * acceleration

F = ma

Force = 20 Newtons

Mass = ?

Acceleration = 1 m/s

Here, we don't need to find the mass. Which is why this is such a tricky question.

Instead, we need to find the force.

Of course, we know already that force doesn't necessarily require a direction.

F = 20 N

The force needed would be 20 Newtons, as said.
