## Answers ( ) • We’re provided – mass ( m ) = 5 kg , initial velocity ( u ) = 10 m / s , final velocity ( v ) = 30 m / s , Time taken ( t ) = 20 sec and we’re asked to find out the amount of force applied.
• Here , we’ll use ‘ F = ma ‘ in order to find out the amount of force applied where ‘ F ‘ refers to Force applied , ‘ m’ refers to mass of the body and ‘ a ‘ refers to acceleration.
• Since we aren’t provided the acceleration , we’re gonna use ‘ v – u / t ‘ where ‘ v ‘ refers to final velocity , ‘ u ‘ refers to initial velocity & ‘ t ‘ refers to time taken.       • Hence , the amount of force applied will be 5 Newton .
