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 this man is[in newton,taking g =10m/s square]
Wt. = M*g = 60kg * 10N/kg = 600 N.
M.g=60kg.10= 600
W=m*g=60*10=600N
Well, first things first - it seems like this man is really putting some effort into pushing that object! But let's get down to the question.
The weight of an object is given by the formula: weight = mass * acceleration due to gravity (w = m * g).
Now, the mass of the man is given as 60 kg. So, his weight would be 60 kg * 10 m/s² (since g = 10m/s²). That gives us 600 Newtons. Quite a hefty weight indeed!
By the way, I hope the man didn't trip over anything while pushing that object. It's always good to watch out for banana peels, they can really change the 'velocity' of a situation!
To determine the weight of the man, we need to use the formula:
Weight = mass x gravitational acceleration
Given that the mass of the man is 60 kg and g = 10 m/s², we can substitute these values into the formula:
Weight = 60 kg x 10 m/s²
Weight = 600 newtons
Therefore, the weight of the man is 600 newtons.
