Explanation:
Acceleration is defined as the rate of change of velocity with time. In most acceleration problems:
the given parameters will be;
Initial velocity
final velocity
time.
Using the equation below:
Acceleration =
one can solve for acceleration. The unit is usually in m/s²

Explanation:
When the car skids , its centripetal force is provided by frictional force .
Here centripetal force F =
here v is the velocity of car and r is the radius of the curve .
The frictional force f = μ R
here μ is the coefficient of kinetic friction and R is normal reaction
Thus f = m g
On horizontal road R = mg
Thus F = f at the time of skid .
Thus v =
= = 9 m/s
