The acceleration-time graph of a particle moving in a straight line is shown in the figure. If the initial velocity of the particle is zero then the velocity-time graph of the particle will be

The acceleration versus distance graph for a particle moving with initial velocity 5 m/s is shown in the figure. The velocity of the particle at x = 35 m will be

In case of projectile motion, which one of the following figures represent variation of horizontal component of velocity (u_x) with time t? (Assume that air resistance is negligible)

A fighter plane, flying horizontally with a speed 360 km/h at an altitude of 500 m drops a bomb for a target straight ahead of it on the ground. The bomb should be dropped at what approximate distance ahead of the target? Assume that acceleration due to gravity (g) is 10 ms^-2. Also, neglect air drag.

Two particles are simultaneously projected in the horizontal direction from a point P at a certain height. The initial velocities of the particles are oppositely directed to each other and have magnitude v each. The separation between the particles at a time when their position vectors (drawn from the point P) are mutually perpendicular, is

At a particular height, the velocity of an ascending body is u. The velocity at the same height while the body falls freely is

A projectile thrown with an initial velocity of 10 ms^$$-$$1 at an angle $$\alpha$$ with the horizontal, has a range of 5 m. Taking g = 10 ms^$$-$$2 and neglecting air resistance, what will be the estimated value of $$\alpha$$?

A train moves from rest with acceleration $$\alpha$$ and in time t₁ covers a distance x. It then decelerates to rest at constant retardation $$\beta$$ for distance y in time t₂. Then,
