A force of 315N is applied to a crate to displace it 35m across a floor at constant velocity The internal energy increases by 14percent of initial internal energy what was the initial internal energy?
1543.5 is the answer w=F*s = 315*35 =11025 this is the final or
total internal energy now use the formula of percentage
14/100=initial internal energy/11025 (14/100)*11025=internal energy
i cannot say with surety that this is right
