A van of mass 2150kg with a driving force of 10,000 is accelerating at 3 m/s^2. Find the resultant force acting in the van, and also the frictional force on the van.

We have values for the mass and the acceleration of the van, so we can work out the resultant force acting on it using Newton’s second law: F_r = ma F­_r­ = 2150 x 3 = 6450N Driving force – Resultant force = Frictional force Frictional force = 10,000 – 6450 = 3550N
