A force equal to wt of 1kg acts on a body continuously for 10s & causes it to move 10m in thay time.find d mass of body???

The force is F = 1 x 9.8 = 9.8 N
Let the mass of the body be m. Then acceleration of the body is 9.8/m
Then, assuming horizontal force, and rectilinear motion,
s = (1/2)at2
10 = (1/2)(9.8/m)100
m = 49 kg

Force of m kg wt = Force of mg N
So, force of 1 kg wt = force of 9.8 N
Acceleration = force/mass = 9.8/m
Apply : s= ut + (1/2)at2
10 = (0)(10) + (1/2)(9.8/m)(102)
m = 49 kg
