Question

A constant force acts on a body of 2kg, mass, due to which it travels a distance of 3m in first second and a further distance of 1 m in the next second. How much force is acting on the body ?
  (1) 4 N   (2) 12 N (3) 8 N   (4) 1 N​

Answer 1

Answer:

2.56kg/gragg ...............

Answer 2

mass=2 kg

here u[initial velocity]=3m/s

        v[final velocity]=1m/s

then a=(v-u)/t

         =(-1-3)/2

          -4m/s^2

then F= m*a

      =2*-4

     =8 N opposite to direction of motion

its your answer buddy

hope this helps
