Question

Do five numericals based on
1 v = u + at
2. S =ut +1/2at^2
3. V^2 = u^2 + 2as

Answer 1

Answer:

1.If a body start running from a point A to point B with acceleration of 2m/s^2 take time 5sec. Find the final velocity of the body.

Solution=

Given,

initial velocity (u)=0

acceleration(a)=2m/s^2

time (t) =5sec

We know that,

v=u+at

v=0+2m/s^2 × 5s

v=10m/s

The final velocity of the body is 10m/s.

2.An object undergoes an acceleration of 8m/s^2 starting from rest . Find the distance traveled in one second.

Solution: u=0, a=8m/s^2, t=1, S=?

Now,. S=ut+1/2at^2

or. S=0+1/2×8×1^2

or. S=4m
