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

a
9.8 m/s2

b
4.0 m/s2

c
22 m/s2

d
0.25 m/s2

1 answer

The acceleration of an object is given by the formula F = ma, where F is the force applied to the object and m is the mass of the object. In this case, the force applied is 220 N and the mass is 55 kg.

Plugging these values into the formula, we get:

220 N = 55 kg * a

To find the acceleration, we can divide both sides of the equation by 55 kg:

220 N / 55 kg = a

Simplifying the equation, we get:

4 m/s² = a

Therefore, the acceleration of the block is 4.0 m/s².

The correct answer is b) 4.0 m/s².
