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?
The work done by the force is calculated as the force applied multiplied by the displacement, which gives W = 315N * 35m = 11025 J. Since the crate is moving at a constant velocity, the work done by the force is equal to the increase in internal energy. Given that the increase in internal energy is 14% of the initial internal energy, we can calculate the initial internal energy as I = 11025 J / 0.14 = 78750 J.
