Physics

Given:
Vf = 0 m/s (final velocity),
a = -3.90 m/s² (acceleration, negative because it represents deceleration),
d = 290 m (length of the skid marks).

To determine the speed of the Jaguar before it began to skid (Vi) , we can use the following equation:

Vf² = Vi² + 2ad

Where:
Vf is the final velocity (which is 0 m/s since the Jaguar skidded to a stop),
Vi is the initial velocity (the speed we want to find),
a is the acceleration, and
d is the length of the skid marks.
