Question

a body travels in a straight line with initial velocity of 2 m/s² . if it's uniform acceleration is 1 m/s² it's velocity at the end of 5 sec is​

Answer 1

Answer:

final velocity=7m/s

Step-by-step explanation:

here

initial velocity (u) =2m/s

acceleration (a) =1m/s^2

time (t) = 5 sec

formula

v=u+at

=2+1(5)

=2+5

=7m/s

velocity at the end of 5 sec is 7m/s

Answer 2

Answer:

The velocity of body at the end of 5 sec is 7m/s

Step-by-step explanation:

Given that,

The body travels in a straight line with an initial velocity of 2m/s.Therefore,

$u = 2ms {}^{ - 1}$

Also given that the uniform acceleration of the body is

$a = 1ms {}^{ - 2}$

We are required to find the velocity at the end of 5 sec.For that we use the equation of motion

$v = u + at$

Substituting the known values,

u=2,a=1 and t=5, we get

$v = 2 + 1(5) = 7ms {}^{ - 1}$

Therefore,The velocity of body at the end of 5 sec is 7m/s
