Answer:
given = force (F) = 400N
speed = 4.0 m/s
time = 3.0sec
to find = mass and weight of body
solution ;-
use the 1st equation of motion,
v = u + at
4.0 = 0 + a × 3
4.0 = 0 + 3a
3a = 4.0
a = 4/ 3
a = 1.33
now use the newtons second law,
mass = force / accelaration
mass = 400 / 1.33
mass = 300 Kg
