Question

An object moves along a straight line with an acceleration of 2 m/s2. If its initial speed is 10 m/s, what will be its speed 2 s later?

Answer 1

Answer:

ANSWER

a=2m/s

u=10 m/s,t=5 sec

v=u+at

v= 10+2×5

v=20m/sec

Answer 2

Given:-

initial velocity(u)= 10m/s

acceleration(a)=2m/s²

time=2s

To find:-

final velocity(v)

Solution:-

By using v=u+at,we get----

v=10+2×2

v=10+4

v=14m/s

Thus,it's speed 2 seconds later will be 14m/s
