A 0.55 kg block is being pulled by a 2.5 n force east across a horizontal frictionless surface what is the acceleration of the block

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force

m is the mass

From the question we have

We have the final answer as

Hope this helps you

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

b would be the answer
