Question

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

Answer 1

hey buddy !! here's your answer...

★ F = ma
a = F/m
a = 6/1
a = 6 m/s²

★ now applying second equation of motion,

s = ut + ½ at²

(u = 0, as body is initially at rest)

s = ½at²

12 = ½ x 6 x t²

4 = t²

t = 2 sec. ✔️✔️

hope it helps !!❤️✌️

bonne journée !! ⭐⭐

Answer 2

m= 1kg

s= 12m

u= 0 m/s

F= 6N

F=m*a

6=1*a

a=6 m/s^2  

v^2=u^2+2a*s

v^2=0+2*6*12

v^2=144

v= 12

=> v=u+at

=> 12=0+6*t

=> t= 12/6

t= 2 sec

so the answer is 2 second
