Answer 1

Answer:

1

Explanation:

in graph a= constant slope= constant velocity=

so, no acceleration and no force(in x axis)

in graph b= varying slope=varying velocity

so, acceleration and force is present(y axis)

using formula, s= it+1/2at²

initial velocity=0

so, ut=0

now, s= 1/2at²

4=1/2a(2)²

a=2m/s²

force= m.a

= 0.5kg×2
