A force F = 5√2 t N is applied on the block as shown in the figure. The block starts from rest at t = 0, then

Q: A force F = 5√2 t N is applied on the block as shown in the figure. The block starts from rest at t = 0, then

Numerical

(a) the block leaves the horizontal surface at t = 20 s

(b) the block never leaves the horizontal surface

(c) the velocity of block at t = 20 s is 100 m/s

(d) Both (a) and (c) are correct

Ans: (d)
