A delivery van has a mass of 2500 kg.
The resultant force on the van is 5000 N.
Use the equation: force=mass×acceleration\text{force} = \text{mass} \times \text{acceleration}force=mass×acceleration
Calculate the acceleration of the van.
Parcels with a total mass of 500 kg are loaded into the van.
The resultant force on the van stays the same.
Calculate the new acceleration of the van.
The mass of the van stays the same, but the resultant force on it doubles.
State what happens to the acceleration of the van.
