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?

4
5
6
3

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
