Question

The speedometer readings of a car are shown below. Find the acceleration of the car and its displacement.
Time Speedometer
9:25 am:18km/h
9:45 am:36km/h

Answer 1

Explanation:

v=36km/hr =36 * 5/18 m /sec

=10 m /sec

u=18km/hr =18 * 5/18 m /sec

=5 m/sec

t= 20 min =20*60 sec =1200 sec

a = v-u/t

= 10-5/1200

= 5/1200

=1/240
