Dalvin pushed a 20kg obiect a distance of 10 meters in 30 seconds. He pushed a 40kg object a distance of 5 meters in 30 seconds. What can you INFER about force and mass from the scenario?

Explanation:

The force applied on a body is given as:

       Force = mass x acceleration

First scenario;

   Mass of object  = 20kg

   distance  = 10m

    time    = 30s

Second scenario;

     Mass of object  = 40kg

     distance  = 5m

      time  = 30s

speed  1 =  =   = 0.33m/s

speed 2  =  =  = 0.167m/s

The first scenario;

       F = 20 a

Second scenario;

       F = 40 a

Momentum of 1 = mass x velocity  = 20 x 0.33  = 6.6kgm/s

Momentum of 2  = mass x velocity  = 40 x 0.167 = 6.68kgm/s

Force  =

 m(v-u) = momentum

From this scenario, the first body has a lesser force and mass compared to the second one because it has a slightly higher momentum.
