Average acceleration: 3 m/s² (0.31 g).

  • The object is gaining speed: its velocity shifts by 3 m/s every second.
  • That equals about 0.31 g (0.31 times Earth's standard gravity of 9.81 m/s²).
  • Over the interval, the object covers roughly 121.5 m of displacement (using s = v_i t + 0.5 a t²).
  • This is the average (or constant) acceleration over the whole interval; instantaneous acceleration may differ if the rate is not uniform.

Next stepMultiply acceleration by the object's mass (F = m × a) to find the net force that produced it.
