IIT JEE : Motion In Two And Three Dimensions QUESTIONS AND ANSWERS :: part1 : 1 to 5

Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2014 examinations :

1.A stone is projected with a velocity of 10 m/s at an angle of 30degree with the horizontal. It will hit the ground after time:

3 s
2 s
1.5 s
1 s

2.The benches of a gallery in a cricket stadium are 1 m high and 1 m wide. A batsman strikes the ball at a level 1 m about the ground and hits a ball. The ball starts at 35 m/s at an angle of 53 degree with the horizontal. The benches are perpendicular to the plane of motion and the first bench is 110 m from the batsman. On which bench will the ball hit?


3.If air resistance is ignored, then the horizontal motion of the oblique projectile takes place at

uniform acceleration
variable acceleration
uniform retardation
uniform velocity .

4.A projectile is thrown into space so as to have maximum possible range of 400 m. Taking the point of projection as the origin, the co-ordinance of the point where the velocity of the projectile is minimum is:

(400, 100)
(200, 100)
(400, 200)
(200, 200)

5.A projectile is projected with kinetic energy of 800 J. If it has the maximum possible horizontal range, then its kinetic energy at the highest point will be

800 J
400 J
200 J
100 J
