a man having a mass of 60 kg exerts a horizontal force of 200 newton in pushing a 90 kg object a distance of 60 meters along horizontal floor. he does this at constant velocity in 3 seconds.the weight of man will be?
the weight of the man is unaffected by all the horizontal pushing and shoving:
mg = 60kg * 9.8 m/s^2 = 588N
I am not getting the questation plzzzzzz give the formula plzzzz
w=mg
To find the weight of the man, we need to understand the concept of weight and how it is related to mass and acceleration due to gravity.
Weight is the force exerted on an object due to gravity. It is calculated by multiplying the mass of the object by the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s².
Now, let's calculate the weight of the man:
Step 1: Find the force required to move the object.
The force required to move the object can be calculated using Newton's second law of motion: force (F) = mass (m) × acceleration (a). Since the object is moving at a constant velocity, the acceleration is zero. Therefore, the force required to move the object is also zero.
F = m × a
F = 90 kg × 0 m/s²
F = 0 N
Step 2: Calculate the net force applied by the man.
The net force applied by the man is equal to the force required to move the object. Since the object is moving at a constant velocity, the net force applied by the man is also zero.
Net Force = Force applied by the man - Force required to move the object
0 N = Force applied by the man - 0 N
Force applied by the man = 0 N
Step 3: Calculate the weight of the man.
The weight of the man is equal to the force applied by the man. Hence, the weight of the man is also zero.
Therefore, the weight of the man will be 0 N.
