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 = . Here t is the time in second. All the 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? (Take g = 10 m/s 2 ) (29) 1/2 N (516) 1/2 N 26 N (89) 1/2 N

V = 5t i˄ + 2t j˄

a = (dv / dt) = 5i˄ + 2j˄

F = ma

F = m [ax i˄ + (g + ay)j˄]

|F| = m √(ax2 + (g + ay)2)

|F| = (2) √(52 + (10 + 2)2)

= (2) √(25 + 144)

|F| = 26 N
