A wheel has a speed of 1200 revolutions per minute and is made to slow down at a rate of $4radians/s^2$ The number of revolutions it makes before coming to rest is
Radius of curved road on a highway is $R$. Width of road is $6$. The outer edge of road is raised by $h$ w.r.t. inner edge so that a car with velocity $\upsilon$ can pass safe over it. The value of $h$ is
From the top of a building a ball is dropped while another is thrown horizontally at the same time. Which ball will strike the ground first?
The vertical component of velocity of a projectile at its maximum height ($u =$ velocity of projection, $\theta =$ angle of projection) is
What is the relationship between time of flight $T$ and horizontal range $R$ ? (where $\theta$ is angle of projection with the horizontal)
A ball is thrown from a point with a speed $v_0$ at an angle of projection $\theta$. From the same point and at the same instant, a person starts running with a constant speed $\frac{v_0}{2}$ to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection?
Parabolic path of a projectile as seen by another similar projectile is.

Two particles are projected simultaneously in the same vertical plane, from the same point, both with different speeds and at different angles with horizontal. The path followed by one, as seen by the other, is
A body is projected vertically upwards from the surface of the earth with a velocity equal to half the escape velocity. If $R$ is the radius of the earth, maximum height attained by the body from the surface of the earth is

A photoelectric surface is illuminated successively by monochromatic light of wavelength ‘(λ)’ and ‘(\(\frac {λ}{2}\))'.
