1. The acceleration of the car is 3.3 m/s²

Explanation:

Given-

Speed of the car, (we can  represent as s) = 60 km/hr = 60 × $$\frac{5}{18}$$ = 16.67 m/s

Time,(we can  represent as  t) = 5 s

Acceleration, (we can represent as a) = ?

We know,

a = $$\frac{s}{t}$$

a = $$\frac{16.67}{5}$$

a = 3.334 m/s²

The acceleration of the car  is 3.3 m/s²
