Question

An object after traveling at a uniform velocity of 4 m/s for 5 sec , travel with a constant acceleration of 0.5m/^2sec in the same direction for another 5 sec . Find the average velocity throughout the journey.

​

Answer 1

Answer:

1 m/s

Explanation:

First find the final velocity using v = u+at formula

= v = 4+(0.5x10)  (we took time as 10 because total time 5+5 which is 10)

=v=9

Find the avg velocity with the formula v-u/t-t or we can say net displacement/final time-initial time

= v avg = 9-4/10-5

= v avg = 5/5

= v avg = 1 m/s
