As soon as a car just starts from rest in a certain direction, a scooter moving with a uniform speed overtakes the car. Their velocity-time graph is a scooter moving with a uniform speed overtakes the car. Their velocity-time graph is As soon as a car just starts from rest in a certain direction August [...]

Figure shows an open tube which contains some water and a less dense liquid poured ino the right hand side. If the density of the unknown liquid is ρx, show that ρx=ρwhwhx Figure shows an open tube which contains some water and a less dense liquid poured ino the right hand side. If the density [...]

Velocity-time graph for a moving object is shown in the figure. Total displacement of the object during the time interval when there is non-zero acceleration and retardation is.

A body is projected horizontally from the surface of the Earth (radius=R) with a velocity equal to n times the escape velocity. Neglect rotational effects of the earth. The maximum height attained by the body from the earth’s surface is R/2. Then n must be A rocket is launched vertically from the surface of earth [...]

The position-time (x-t) graphs for two children A and B returning from their school O to their homes P and Q respectively are shown in Fig. above. Choose the correct entries in the brackets below : (a) (A/B) lives closer to the school than (B/A) (b) (A/B) starts from the school earlier than (B/A) (c) [...]

A rocket is launched vertically from the surface of earth with an initial velocity v. How far above the surface of earth it will go? Neglect the air resistance.

The position versus time graph for a certain particle moving along the x-axis is shown in the figure. Find the average velocity in the time intervals (a) 0 to 2 s, (b) 2 s to 4 s, and (c) 4 s to 7 s. (b) 2 s to 4 s and (c) 4 s to [...]

Let us consider a boat which moves with a velocity v bw ​ = 5 km/h relative to water. At time t=0, the boat passes through a piece of code floating in water while moving downstream. If it turns back at time t=t 1 ​ when and where does the boat meet the cork again? [...]

For a particle projected in a transverse direction from a height h above earth’s surface, find the minimum initial velocity so that it just grazes the surface of earth such that path of this particle would be an ellipse with centre of earth as the farther focus, point of projection as the apogee and a [...]
