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?
a
22 m/s2
b
0.25 m/s2
c
4.0 m/s2
d
9.8 m/s2
c
4.0 m/s2
To find the acceleration of the block, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass:
acceleration = net force / mass
Given:
mass = 55 kg
force = 220 N
Plugging in the values, we get:
acceleration = 220 N / 55 kg
Simplifying the equation, we find:
acceleration = 4.0 m/s^2
Therefore, the correct answer is c) 4.0 m/s^2.
To find the acceleration of the block, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula for this law is:
a = F/m
where a represents acceleration, F represents the force applied, and m represents the mass of the object.
In this case, the force applied is given as 220 N, and the mass of the block is given as 55 kg. Plugging these values into the formula, we get:
a = 220 N / 55 kg
Simplifying the equation, we find:
a = 4 m/s^2
Therefore, the correct answer is option c) 4.0 m/s^2
