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. 22 m/s2
b. 4.0 m/s2
c. 9.8 m/s2
d. 0.25 m/s2
To find the acceleration of the block, we can use Newton's second law of motion:
\[F = ma\]
Where F is the force acting on the block, m is the mass of the block, and a is the acceleration of the block.
In this case, the force acting on the block is 220 N to the right, and the mass of the block is 55 kg. Plugging these values into the equation, we get:
\[220 = 55a\]
Solving for a, we get:
\[a = \frac{220}{55} = 4.0 \, \text{m/s}^2\]
Therefore, the acceleration of the block is 4.0 m/s2, which corresponds to option (b).
