1.	A 1.5 kg block placed on a frictless orizontal floor is pulled by a force F Direction of the force is unchanged and its magnitude is incrcresaed with time according to the equation F =0.5t n where t denotes time in second . Which of the following is /are correct for subsequunt motion after t=0 s? [g=10m//s^(2)]
Answer» The block LEAVES the FLOR at the instant t=50s. Acceleration of the block at the innstant t=40s. `8m//s^(2)` TOWARDS the right . Normal reaction from the GROUND on the block at the instant t=50 s is 8 N. Acceleration vectorof the block at the instant t=80s. Is `(1.3hati +6hatj ) m//s^(2)`. Answer :a,d
