Question

a body of mass 1kg is kept at rest . A constant force of 6n starts acting on it, find the time taken by the body to move through a distance of 12m.

Answer 1

the time taken by body is 2second as speed equal to distance upon time so time will go other side and will divide and speed or Newton force will come this side and divide

Answer 2

Solution)

Given -:
 
Mass (m) = 1 kg
Force (f) = 6 N
Distance (s) = 12 m

Since F = m*a

6 N  =  1 kg * a
a = 6 N / kg
a = 6 m/s ²

Since) s = u * t + 1/2 a * t²

12m = 0 + 1/2 * 6 * t ²
12 m = 3 * t ²
t ² = 12/3
t ² = 4
t = 2

Answer = The body took 2 seconds to move through a distance of 12m.
