Answer :-
Given :-
- Initial velocity = 0 m/s
- Mass = 1 kg
- Force = 6 N
- Distance = 12 m
To Find :-
- Time taken
Solution :-
To find time, we first need to find acceleration and then substitute the value of given in the second equation of motion -
➩ Force = Mass × Acceleration
➩ 6 = 1 × a
➩ a = 6 m/s²
- u = 0
- a = 6 m/s²
- s = 12 m
Substituting the value in 2nd equation of motion :-
➩ s = ut + 1/2 at²
➩ 12 = 0 + 1/2 × 6 × t²
➩ 12 = 3t²
➩ t² = 12/3
➩ t² = 4
➩ t = 2 sec
Time taken = 2 sec
