A horizontal wax bar B rests between a wedge and a vertical wall as shown in the figure. The wedge starts moving towards the wall with a constant acceleration 0. The moment the wedge starts moving, a continuous supply of heat from the wall starts melting 1. If the bar always remains horizontal, which of the following conclusions can you make?

Which of the following conclusions can be drawn? Three ants A, B and C are crawling on a large horizontal tabletop always occupying vertices of an equilateral triangle, size of which may vary with time. Components along and perpendicular to a position vector are known as radial and transverse components respectively.

A particle is projected horizontally from the top a tower. Assume acceleration due to gravity to be uniform and the origin of the coordinate system at the point of projection. Questions 24 and 25 are based on the following physical situation.

Questions 26 to 28 are based on the following physical situation. In a convoy on a long straight level road, 50 identical cars are at rest in a queue at equal separation 10 m from each other as shown.

When an order is given to start the convoy, the first car starts immediately and each subsequent car start when its distance from a car that is immediately ahead becomes 35 m. When an order is given to stop the convoy, the driver of the first car applies brakes immediately and driver of each subsequent car applies brakes with a certain time delay after noticing brake light of the front car turned red. When all the cars are moving at the maximum speed, what is the separation between two adjacent cars?

During the time when motion is building up in the convoy, some of the cars are moving and the others are at rest. What is the average rate of change in length of the segment consisting of stationary cars? When all the cars are moving at the maximum speed, an order is given to stop the convoy. If all the cars decelerate at equal constant rates and Kinematics of Translational Motion 1.

A hot air balloon of constant ascent velocity can be used to investigate wind velocities at various altitudes. Since wind velocity was almost zero up to a height of approximately 30 m that day, the balloon first rose upwards and then due to horizontal drift caused by the wind it followed a plane curvilinear path. During continuous tracking of the balloon, the telescope has been rotated in a vertical plane without change in azimuth.

A graph depicting how the angle of elevation varies with time thus obtained is shown in the figure. Questions 32 to 35 are based on the following physical situation. It is desired to move another particle C always maintaining a distance 40 m from the particle A and 30 m from the particle B. When and for how long can the particle C fulfil the given condition?

At the instant, when the line joining locations of A and B is perpendicular to the line joining locations of B and C, what are the magnitudes of velocities of C relative to A and B respectively?

One day you were on a picnic with your class. How long did it rain? There is a narrow bridge somewhere on a road connecting two towns. The signals are synchronized in such a way that at a time, alternate signals remain red and the other remain green. The scheme is shown in the following figure. A traffic officer receives complaints on frequent traffic jams at a traffic signal on the main street of a busy market.

He studied the traffic pattern and to simplify calculations made a reasonable assumptions that all the vehicles are identical in size and move with identical speeds. An engineer designs a robot that can climb stairs. This dependence is shown in the following graph. An ant wants to cross the groove. A boy decides to help the ant making a bridge consisting of straight wire segments. A particle covers a distance unidirectionally with uniform acceleration.
