A toy car initially moving with a uniform velocity of 18 km h -1 comes to a stop in 2 s. Find the retardation of the car in S.I. units.

As we know, Given, Initial velocity (u) = 18 km h -1 To convert initial velocity u to m s -1 Hence, 18 km h -1 is equal to 5 m s -1 . Final velocity (v) = 0 Time (t) = 2 s Substituting the values in the formula above, we get, Hence, acceleration of the body is -2.5 m s -2 . Negative sign shows that the velocity decreases with time, so retardation is 2.5 m s -2 .

A car starting from rest acquires a velocity of 180 m s^-1 in 0.05 h. Find the acceleration.
