A cyclist decelerates uniformly at 0.4 m `s^(-2)` from velocity 5 m `s^(-1)` to a complete stop. How long does he take to stop?

To solve the problem of how long the cyclist takes to stop, we can use the equations of motion. Here’s a step-by-step solution: ### Step 1: Identify the known values - Initial velocity (u) = 5 m/s (the speed at which the cyclist starts) - Final velocity (v) = 0 m/s (the speed when the cyclist comes to a complete stop) - Deceleration (a) = -0.4 m/s² (deceleration is negative acceleration) ### Step 2: Use the equation of motion ...
