A block of mass 3.0 kg is pulled at a constant speed with a taut rope along a frictionless plane that is inclined at 30°. Then the work done by the weight of the block if it is pulled a distance 4 m along the inclined plane in joule is [Acceleration due to gravity = 10 m s$^{-2}$]:

A block of mass 20 kg is connected to the top of an inclined plane by a spring of negligible mass, unstretched length 0.7 m and spring constant 200 N m$^{-1}$. How far is the block from the top along the incline in the equilibrium point? The inclined plane is frictionless and the angle of inclination is 30°. (Take g = 10 m s$^{-2}$)

Masses \(\frac{1}{2}\) are placed at \(x = N\) on the x-axis where \(N = -1, 0, 1, 2, \dots\). If the total mass of the system is M, then the position of the centre of mass of the system is:

Statement [A]: If a body is in equilibrium, then the resultant of the forces acting on the body is zero. Statement [B]: Action and reaction cancel each other as they act on the same body. Statement [C]: Centrifugal force is a pseudo force.

Two particles A and B are moving along positive x- and positive y-axes respectively with the same speed v m s$^{-1}$. At t = 0, they both pass through the origin. The equation of the straight line joining A and B at time t is:

A truck carrying sand having a total mass of 1600 kg is moving with a uniform velocity of 15 m s$^{-1}$. Sand is dropped into it at a rate of 24 kg min$^{-1}$. The force needed to keep the truck moving with uniform velocity is:

Four athletes A, B, C and D in a long jump competition each running at a speed of 30 km h$^{-1}$. While jumping, they make angles of 30°, 45°, 60° and 75° with the ground respectively. Then the winner of the competition is:

A person is running with a uniform velocity towards a flyover. He takes 5 s to reach the flyover from a reference point and takes 50 s to cross the flyover from the same reference point. If the length of the flyover is 1000 m, then his velocity is nearly:
