Figure shows (x,t) (y,t) diagram of a particle mTwo blocks A and B of masses 2.9kg and 1.9kg respectively are suspended with the help of two inextensible wires each of the length 1m from a rigid support as shown in the figure. The mass of the upper wire is negligible and that of the lower wire 0.2kg/m. This system of block, wires and rigid support is moving upwards with an acceleration of 0.2m/s2. The tension at the midpoint C and D of the lower and the upper wires will be respective in 2 dimensions. If the particle has a mass of 500 g, the force acting on the particle is-duplicate-5

The rear side of a truck is open and a box of 40kg mass is placed 5m away from the open end as shown in the figure. The coefficient of friction between the box and the surface below it is 0.15. On a straight road, the truck starts from rest and accelerates with 2ms−2. Find the distance (in m) traveled by truck by the time box falls from the truck. (Ignore the size of the box)
