A body weighing 1 kg moves uniformly in a straight line at a speed of 50 cm / s.

A body weighing 1 kg moves uniformly in a straight line at a speed of 50 cm / s. Find the resultant of all forces applied to the body.

The resultant of all the forces that are applied to the given body will be equal to zero, since the movement of the body is uniform and rectilinear, i.e. V (body speed) = const = 50 cm / s = 0.5 m / s and a (acceleration) = V ‘= 0.5’ = 0 (F = m * a = 1 * 0 = 0 N). This can also be seen from the modern formulation of Newton’s first law.

Answer: The net effect of all forces applied to the body is zero.
