Question

6. The speed a of Car as a function of Time is shown in the following figure find find the distance Travelled by Car in 8 seconds and its alleleration / 20- speed in m/s 10+ 2 4 6 3 3 ID Time in second​

Answer 1

In the inerval 8 sec the velocity changes from 0m/s to 20 m/s. Average accelerationn `=20/8 m/s^2

=2.5 m/s^2 ((change in velocity )/time)

Distance travelled,

S=ut+12at2=0+12(2.5)82=80m
