Newton's second law for an object's motion in one spatial dimension:
F = ma
F is the force, m is the mass, and a is the acceleration.
From this equation, we can tell that, compared to a less massive object, a more massive object will need a bigger force to make it accelerate at the same rate. The 30kg sofa has the most mass out of all the above listed objects, therefore it will take the biggest force to accelerate at 1m/s²
Choice D
Work is done only when there is a displacement of the object on which a force is applied in the direction of the force.
Answer:
The value is 
Explanation:
From the question we are told that
The angular speed is 
The distance between the minimum and maximum external position is 
Generally the amplitude of the crank shaft is mathematically represented as
=> 
=> 
Generally the maximum speed of the piston is mathematically represented as
=> 
=>
The answer is 4.7 m for the spàthan. this is a very question! I hope this helps my friend! :-)
