Question

For a body traveling with uniform acceleration it's final velocity V=root 180-7x where x is the distance traveled by the body 8n meters. Then the acceleration is​

Answer 1

Answer:

Let initial velocity =u and a(uniform acceleration),v=

180−7x

x=distance traveled

By applying third equation of motion,

v

2

=u

2

+2as

⟹(

180−7x

)

2

=u

2

+2as

⟹180−7x=u

2

+2ax

On comparing both sides, u

2

=180 and 2a=−7

⟹a=−3.5m/s
