A constant force acts on an object of mass 6 \(kg\) for a duration of 3 \(s\). It increases the object’s velocity from 4 ms1 to 7 ms1. Find the magnitude of the applied force. Now, if the force was applied for a duration of 10 \(s\). (Enter the values up to two decimal)
  
what would be the final velocity of the object?
 
Answer:  ms1
