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 12m ​

Answer 1

Answer:

Time taken= 2s

Explanation:

Force = Mass × Acceleration

6N = 1kg × a

6m/s2 = a

Using Second equation of motion

s = ut + 1/2at2

12 = 0(t) + 1/2* (6)* t2

12 = 3t2

4 = t2

t = √4

= +2 or –2 ; as time can’t be negative so, positive value of time is taken.

2s = t

 Therefore, time taken is 2s.
