Answer 1

B) 4 m/s²

Step-by-step explanation:

• Since the surface it's kept on is frictionless, the net external force acting on the block will be 220 N.
• Mass of the block = 55 kg

`\boxed{ \sf{ F= m * a}}`

Here,

• F is the net external force applied to an object,
• m is the mass of that object, and
• a is the acceleration it acquires.

Substituting the respective values for F and m:

==> 220 = 55 × a

==> 220 = 55 × a

dividing the equation by 55:

==> 4 = a

Therefore, an object of 55 kg when pulled across a frictionless surface by a force of 220 N accelerates at 4 (m/s)/s
