A truck of mass `M` is moved under a force `F`. If the truck is then loaded with an object equal to the mass of the truck and the driving force is halved, then how does the acceleration change?

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.

A block of mass 1kg lies on a horizontal surface in the truck, the coefficient of friction between the block and the surface is 0.6. If the acceleration of the truck is 5ms^(-2) the frictional force acting on the block is

A block of mass m is attached to a massless spring of force constant k, the other end of which is fixed from the wall of a truck as shown in figure. The block is placed over a smooth surface and initially the spring is unstretched. Suddenly the truck starts moving towards right with a constant accleration a_(0). As seen from the truck

A truck of mass 10 metric ton runs at 3ms^(-1) along a level track and collides with a loaded truck of mass 20 metric ton, standing at rest. If the trucks couple together , the common speed after the collision is
