The object's velocity accelerating from rest from the applied force and time is closest to 4 m/s.

Velocity of the object

The velocity of the object can be determied by applying Newton's second law of motion as shown below;

F = ma

where;

  • F is the applied force
  • m is the mass of the object
  • a is the acceleration of the object

The acceleration of the object is calculated as follows;

a = F/m

at time, t 4.0 s, the corresponding force = 2 N

a = 2/2

a = 1 m/s²

Velocity of the object is calculated as;

v = u + at

v = 0 + 1 x 4

v = 4 m/s

Thus, the object's velocity accelerating from rest from the applied force and time is closest to 4 m/s.
