Question

A force of magnitude ‘F’ acts on a body of mass ‘m’ at rest for time ‘t’ which travels a distance ‘x’ and
attains a velocity ‘v’. Prove that,
V = rootover2Fx/m and t = rootover2mx/f​

Answer 1

Answer:

mx/t²

Explanation:

Given : u=0

Let the velocity of body after t seconds be v.

Using v=u+at where a=

m

F

∴ v=0+

m

F

t ⟹v=

m

Ft

Distance covered in another t seconds x=vt

∴ x=

m

Ft

t ⟹F=

t
