SUMMARY
The discussion focuses on calculating the rate of deceleration and the time required for a truck to decelerate from 40.0 m/s to 20.0 m/s over a distance of 100 m. The relevant equations include \(s = ut + \frac{1}{2}at^2\) and \(v^2 = u^2 + 2as\). By applying these equations, one can derive both the deceleration and the time taken for the truck to cover the specified distance. The solution involves substituting known values into the equations to find the unknowns.
