The mass of the van will be 2.5 kg, Mass is found as the ratio of the force and the acceleration.
<h3>What is force?</h3>
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.
Force is defined as the product of mass and acceleration. Its unit is Newton.
F=ma
5.5 kN = m × 2.2m/s²
m= 2.5 kg
Hence,the mass of the van will be 2.5 kg,
