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.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
