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=5ti + 2tj . Here t is in second . All surface are smooth . The sphere is at rest with respect to the cube . What is the total force exerted by the sphere on the cube .

Text Solution

Verified by Experts

`v=5ti + 2tj , bar(a) = (dv)/(dt) = 5i + 2j`
` F = ma_x hati + m(g +a_y) hatj , F=2(5i) + 2[10+2]hatj` ,
`F=10i + 25 j , F= sqrt(100 + 567) = sqrt(676) = 26N`
