FIGURE shows four electric charges located at the comers
Chapter 3, Problem 44P(choose chapter or problem)
a. Suppose you are driving at speed \(v_{0}\) when a sudden obstacle in the road forces you to make a quick stop. If your reaction time before applying the brakes is \(t_{R}\), what constant deceleration (absolute value of \(a_{\mathrm{x}}\) ) do you need to stop in distance \(d\)? Assume that \(d\) is larger than the car travels during your reaction time.
b. Suppose you are driving at \(21 \mathrm{~m} / \mathrm{s}\) when you suddenly see an obstacle \(50 \mathrm{~m}\) ahead. If your reaction time is \(0.50 \mathrm{~s}\) and if your car's maximum deceleration is \(6.0 \mathrm{~m} / \mathrm{s}^{2}\), can you stop in time to avoid a collision?
