Question

A solid sphere of mass 2 text end text k g is resting inside a cube as shown in the figure. The cube is moving with a velocity stack v with rightwards arrow on top equals left parenthesis 5 t i plus 2 t stack j with hat on top right square bracket right parenthesis m s to the power of negative 1 end exponent Here t is the time in scond. All surfaces are smooth. The sphene is at rest with respect to the cube. what is the total force exerted by the sphene on the cube (g=10ms-2) )
