The work done against the gravitational force goes into an important form of stored energy that we will explore in this section. ... If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh.
Well little kids i think are trying to pull down a adult but only the adult will only move a smudge so i guess there will be no movement? this may be wrong so i don’t know sorry if u get it wrong
To solve this problem we will apply the concepts related to Newton's second law for which the product of mass and acceleration is defined as the force applied to an object. Mathematically this is,
Here,
Net external Force
m = Mass of the body
a = Acceleration
The net force on the body would be given by the difference between the ascending force and the weight, therefore,
Here,
F = Upward Force
W = Weight
The Weight is,
Then the is
Finally replacing at the first equation we have,
Therefore the acceleration of the stone is
If I'm right you bring in newtons second law which is F=ma
you rearrange to a=F/m
so 18/5 (33-15 - unbalanced forces)
acceleration is 3.6m/s squared
Answer: continental-continental convergent boundary
