A block of mass 2 kg is placed on a truck as shown in the figure. The coefficient of friction between the block and surface is 0.5 . The truck starts from the rest and moves with acceleration a_(0) . (a) Find the friction force acting on the block if (i) a_(0) = 2 m//s^(2) , (ii) 4 m//s^(2) , (iii) 6 m//s^(2) and (b) if acceleration of truck a_(0) = 8 m//s^(2) . After how much time the blocks falls off the truck and the distance travelled by the truck in this time.

Two particles are shown in figure. At t = 0 a constant force F = 6 N starts acting on 3 kg . Find the velocity of circle of mass of these particle at t = 5 s . .

I started climbing up the hill at 6 am and reached the temple at the top at 6 pm. Next day I started coming down at 6 am and reached the foothill at 6 pm. I walked on the same road. The road is so short that only one person can walk on it. Although I varied my pace on my way, I never stopped on my way. Then which of the following must be true
