The complete question is as follows: A student is subjected to a reaction force of 10 N northward from a 5 kg block while pushing the block over a smooth, level surface. Ignoring friction, what is the acceleration of the block?
Answer: The acceleration of the block is .
Explanation:
Given: Force = 10 N
Mass = 5 kg
It is known that force applied on an object is the product of mass and acceleration.
Mathematically,
where,
F = force
m = mass
a = acceleration
Substitute the values into above formula as follows.
Thus, we can conclude that the acceleration of block is .
initial angular speed is given by 33.3 rpm
final angular speed is given by 78 rpm
now by using kinematics we will have
