The  range R of projectile is same when its maximum height are h₁ and h₂. What is the relation between R, h₁ and h₂?  

A projectile is fired from level ground at an angle θ above the horizontal. The elevation angle of the highest point as seen from the launch point is related to θ by the relation   

A projectile has a time of flight T and range R. For a given angle of projection if the time of flight is doubled, then what happens to the range?   

hree particles A, B and C are projected from the same point with the same initial speeds making angles 30^o, 45^o and 60^o respectively with the horizontal. Which of the following statements is correct?  

A particle is projected from the ground with an initial speed of v at an angle q with horizontal. The average velocity of the particle between its point of projection and highest point of trajectory is

A particle is moving along a circular path. The angular velocity, linear velocity, angular acceleration and centripetal acceleration of the particle at any instant respectively are   . Which of the following relations is not correct?  

A particle is moving along a circular path with uniform speed. Through what angle does its angular velocity change when it completes half of the circular path?  

A wheel is subjected to uniform angular acceleration about its axis. Initially its angular velocity is zero. In the first 2 sec, it rotates through an angle q1; in the next 2 sec it rotates through an additional angle θ₂, the ratio θ₂/θ₁ is   

If the equation for the displacement of a particle moving on a circular path is given by  θ  = 2t³ + 0.5 where θ is in radian and t in second, then the angular velocity of the particle at  t = 2 s is  

Which of the following statements is false for a particle moving in a circle with a constant angular speed?

Two trains are each 50 m long moving parallel to each other at speeds 10 m/s and 15 m/s respectively, at what time will they pass each other?  

Two cars are moving in same direction with speed of 30 kmph. They are separated by a distance of 5 km. What is the speed of a car moving in opposite direction if it meets the two cars at an interval of 4 min?   

A man can swim in still water at a speed of 6 kmph and he has to cross the river and reach just opposite point on the other bank. If the river is flowing at a speed of 3 kmph, and the width of the river is 2 km, the time taken to cross the river is (in hours)
