Question

A body moving with a constant acceleration Travels the distance 3 m and 8 M respectively in 1 seconds and 2 seconds calculate the initial velocity and the acceleration of the body

Answer 1

Hi..

Heres ur answer..
Hope this helps u!!

Answer 2

d_{1} = 3 m
t_{1} = 1 sec
d_{2} = 8 m
t_{2} = 2 sec

s = ut +  \frac{1}{2} at^{2}
For s = 3 and t = 1
3 = u * 1 +  \frac{1}{2} at^{2}   (i)
For s = 8 and t = 2 
8 = 2 * u  + 0.5 * a * 4  (ii)
Solving i and ii we get u = 2 m/s and a = 2m/s^{2}
