Answer:
B) 4 m/s²
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
[tex] \boxed{ \sf{ F= m \times a}}[/tex]
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
