) An object with a mass of 10 kg is initially moving at an initial velocity V¡ =10 m/s. It is acted upon by an external force (E) for a period of 20 seconds (s). At the end of that time interval (A t), its final velocity (V;) is 30 m/s. Find the acceleration of the object (A) caused by the force. We can calculate acceleration using A = ( V1 - Vj) / a t. ) Use F = MA to calculate the magnitude of the force on the object in Newtons (N).
