What force, in newton, your muscles need to apply to hold a mass of 5kg in your hand? State the assumption.

Given: m=5kg,

F=mg

= (5) (9.8)

= 49N

The value of acceleration due to gravity assumed is 9.8m/s2

hello everyone welcome to leader learning i am good breed your science tutor today's question is what force in newton your muscles need to apply to hold a mass of 5 kg in your hand state the assumptions so in this the mass is given as 5 kg and you have to calculate the force in newton's force is given by the formula m into g okay so m is 5 and g is 9.8 meter per second square then you will get the value of force as 49 newtons okay the value of acceleration due to gravity assumed here is 9.8 meter per second square this is your final answer for more such videos please subscribe leader learning and for any doubts drop a comment thank you
