Question

The body of mass 1 kg is kept at rest. A constant force of 6.0 N acting on it the time taken by the body to move through a distance of 12 m

Answer 1

Time taken by the body to move through a distance of 12 m is 2 s

Explanation:

using the equation for force

$F= m a$

m= mass= 1 kg

F= force= 6 N

a= acceleration=

6= 1 a

a= 6 m/s²

Now using the kinematic equation,

$d= Vt + \frac{1}{2} at^2$

d= distance= 12 m

V= initial velocity=0 as the object is at rest initially

12= 0(t)+ 1/2 (6) t²

t²=4

t= 2 s
