If two stones projected from the same point with the same speed but at angles 3π and 6π respectively have their ranges R1 and R2 than:
R1=2R2
R1=R2
R1=5R2
R1=25R2
In projectile motion, if air resistance is ignored, the horizontal motion is at:
Constant acceleration
zero acceleration
variable acceleration
variable velocity
Two balls A and B are thrown from a running train. Ball A is just dropped while thrown horizontally outwards, which of the two balls that reach the ground first:
Ball A
Ball B
Not enough information
Both reach at the same time
Which sport does not apply the projectile motion concept?
A projectile is fired horizontally 2000m above the ground. What is the acceleration experience during the motion?
4.5 m/s2
9.8 m/s2
8.9 m/s2
0 m/s2
The horizontal range of a projectile motion depends on the
Initial velocity and angle of projection
Acceleration
Final velocity
None of the above
A projectile has
Minimum velocity at the point of projection and maximum at the maximum height
Maximum velocity at the point of projection and minimum at the maximum height
same velocity at any point in its path
Maximum velocity at the point of projection and zero at the maximum height
A ball is thrown at an angle of 30o to the horizontal. It falls on the ground at a distance of 90 m. If the ball is thrown with the same initial speed at an angle 30o to the vertical, it will fall on the ground at a distance of
120 m
27 m
90 m
30 m
A projectile is thrown with speed 40 m/s at angle θ from horizontal. it is found that projectile is at the same height at 1s and 3 s. Wat is the angle of projection?
tan−1(21)
tan−1(31)
tan−1(3)
tan−1(2)
The maximum height attained by a projectile is increased by 10% by increasing its speed of projection, without changing the angle of projection. The percentage increase in the horizontal range will be:
20%
15%
10%
5%
