A point object is released at t = 0, from a point A (0, 24 m) as shown in the figure. The plane mirror is fixed at angle 45o from vertical. Distance between the object and image will be \(4 \sqrt{2} \mathrm{m}\)at
(use g = 10 ms-2)

A car completes a certain journey in 8 hours. It covers half the distance at 40 km/hr and the rest at 60 km/hr. The length of the journey is...

A ball is thrown from the ground to clear a wall 3 m high at a distance of 6 m and falls 18 m away from the wall. Find the angle of projection of ball.

For a given velocity, a projectile has the same range RR for two angles of projection. If t₁ and t₂ are the time of flight in the two cases, then:

Velocity-time graph of a particle moving in a straight line is shown in the figure. Find the total displacement of the particle.

Wind is blowing west to east along two parallel tracks. Two trains moving with same speed in opposite directions have the relative velocity with respect to wind in the ratio 1:2. The speed of each train is

A body is released from the top of the tower of height H. It takes t time to reach the ground. The position of body t/2 time after release will be

A particle aimed at a target, projected with an angle 15o with the horizontal is short of the target by 10 m . If projected with an angle of 45o is away from the target by 15 m, then the traget by 15 m, then the angle of projection to hit the target is:

A police party is moving in a jeep at a constant speed V. They saw a thief at a distance x on a motorcycle which is at rest. The moment the police saw the thief, the thief started at constant acceleration a. Which of the following relations is true if the police is able to catch the thief?

A bird files with a speed v=|t−2|m/s along a straight line, where t is the time in seconds. The distance travelled by the bird during first four seconds is equal to
