Question

AN OBJECT MOVES AIONG ASTRAIGHT LINE WITH AN ACCELERATION OF 2m/s2 IF ITS INITIAL SPEED IS 10M/S 2 WHAT WILL BE ITS SPEED 2SECOND LATER

Answer 1

Given that,

u=10m/s, v=?m/s, a=2m/s^2, t=2 seconds

We have,a= v-u/t

2=v-10/2

2×2=v-10

4+10=v

v=14m/s

Hence,its final speed or velocity is 14m/s.
