A block with a mass of 55 kg is pulled with a force of 220 N. Assuming a frictionless surface, what will be the acceleration of the block?

The acceleration of the block will be 4 m/s^2. This can be calculated using the equation a = F/m, where a is the acceleration, F is the force, and m is the mass. In this case, a = 220 N/55 kg = 4 m/s^2.
