Question

a body of mass 1 kg is kept at rest a constant force of 6 Newton start acting on it find the time taken by the body to move through a distance of 12m

Answer 1

acceleration produced by 6 N= 6/1 =6ms^-2
distance to be travelled =12m
using Newton's 2nd law of motion,
s = ut + at^2/2 where,
u=0 ,a=6,s=12
6*t*t/2 =12
3*t*t=12
t^2 =4
t= 2sec

Answer 2

HEYA!!

-----------------------------------------------------------------------------------------------------
✨Given that

Mass : 1 kg

Force : 6 N .

Acceleration :

Using the formula

F =ma

6 = 1 × A

Acceleration = 6ms-2.

----------------------------------------------------
---------------------------------------------------

Now ,

Initial velocity u =0 { body is at rest }

Distance s = 12 m .

Time taken = ?

Using second equation of motion ,

$s = ut + \frac{1}{2} at {}^{2}$
12 = 0 × t + 1/2 × 6 × (t)^2

12 = 3 t^2

3 t^2 = 12

t^2 =4
T = 2 seconds .
