This information could be used in the following ways: the braking distance of a skidding car will depend on its initial speed and the coefficient of kinetic friction.
Thus, if the coefficient of friction is known the initial speed can be determined from the length of the skid marks.
What do you mean by Initial speed?
Initial speed can be described as how fast an object travels when gravity first applies force on the object. It can be represented in the form of (u) and is generally measured in metres per second (m/s).
It can be represented in three ways.
- v2=u2+2as
- v=u+at
- s=ut+0.5at2
Through these formulas we can calculate the initial speed of any object. It helps in understanding various velocities, time principles.
