Question

A solid sphere of mass 2 kg is resting inside a cube as shown in the figure. The cube is moving with a velocity v with not stretchy rightwards arrow on top equals left parenthesis 5 t i plus 2 t ȷ with not stretchy hat on top right parenthesis ms to the power of negative 1 end exponent Here  is the time in second. All surfaces are smooth. The sphere is at rest with respect to the cube. what is the total force exerted by the sphere on the cube(g=10ms-2)

  1. square root of 29 space N
  2. 29 N
  3. 26 N
  4. square root of 89 space end root space N

The correct answer is: 26 N
