Read the following activity and answer the questions given below:
 
Activity: Push an empty toy cart and then push the same cart loaded with books using the same amount of force.

Observation :
The empty cart moves faster and gains more acceleration.
The loaded cart moves slower and gains less acceleration.
The loaded cart requires greater force to move with the same acceleration as the empty cart. When more force is applied, the cart accelerates faster.
The acceleration of an object depends on both the force applied and the mass of the object.
 
Which cart showed greater acceleration when the same force was applied?
