If the time-displacement graph of a particle is parallel to time-axis, the velocity of the particle is

Write down the equation of the straight line passing through the origin which makes an angle 60^@ with positive x-axis.

A ball moving with a speed of 9m.s strikes an identical ball at rest, such that direction fo eahc ball makes an angle 30^@ with the original line. Find the speed of two ball after collision.

The speed time graph for a car is shown in the figure. Which part of the graph represents uniform motion of the car?

An aeroplane when flying at a height of 3125mfrom the ground passes vertically below another plane at an instant when the angles of elevation of the two planes from the same point on the ground are 30° and 60° respectively. Find the distance between the two planes at the instant.

Find the equation of the straight line which cuts the Y-axis at the point (0, -2) making an angle of 30^@ with OX.

The distance between two poles of the same height standing on the same plane is 100m.The angles of elevation of the tops of the two poles from a point lying on the line joining the base-points of the poles are found to be 30^@ and 60^@ respectively.Find the heights of the poles and the position of the point.

The angle of elevation of the top of a temple from a point in the same horizontal plane is 30^@ .When observed from another point which is 150m straight ahead of the original point on the same plane,the angle of elevation of the top of the temple was 60^@ .Find the height of the temple.
