Question

an object moves along a straight line with an acceleration of 2 m/s2 . if its intial speed is 10m/s what will be speed 2second later

Answer 1

Answer:

Explanation:Given: u=10m/s, a=2m/s2 ,t=2 ,v=?

Using v-u/t =a

v-10/2=2

v-10=4

Thus v=14m/s

Answer 2

Answer:

14 m/s

Explanation:

Given a=2m/s

Initial velocity, u=10m/s

Time,t =2s

A =v-u/t

V=at+u

2*2+10

4+10

=14
