Question

The speedometer readings of a car are shown below. Find the acceleration of the car and its  displacement.. Time. Speedometer. 9:25 am. 72 km/h. 9:45 am. 36 km/h​

Answer 1

we know that⤵⤵

a = $\huge\bf\frac{v-u}{t}$
time =9:25 to 9:45

20 min = 1/3 hours

a = $\bf\frac{36-72}{1}×{{3}}$

a = -36 × 3

a = -108 m/s²
