H

The Figure shows velocity/time graphs for the same car driven by two drivers, X and Y. Each driver sees a stationary obstacle 55 m ahead at time = 0.

Driver Y is distracted.

Figure

a.

Calculate the deceleration of the car while it is braking.

[2]
b.

Determine whether each car stops before it reaches the obstacle.

[4]
c.

Calculate the speed of the car driven by driver Y when it reaches the obstacle.

Use the equation

v2−u2=2×a×xv^2 - u^2 = 2 \times a \times xv2−u2=2×a×x
