Identical guns fire identical bullets horizontally at the same speed from the same height above level planes, one on the Earth and another one on the Moon. Which of the following statement are "TRUE"?
I) The horizontal distance travelled by the bullet is greater for the moon.
II) The flight time is less for the bullet on the Earth.
III) The velocities of the bullets at impact are the same.
I) The horizontal distance travelled by the bullet is greater for the moon.
II) The flight time is less for the bullet on the Earth.
III) The velocities of the bullets at impact are the same.
View answer and explanation
Correct option: C
I and II only
Option C (I and II only) is correct because the horizontal distance is greater on the Moon due to lower gravity, and the flight time is less on Earth due to higher gravity.

Given, The angle between is
Assertion: The necessary condition for motion in two dimensions, velocity and acceleration vectors should have any angle between and between them.
Reason: For two-dimensional or three-dimensional motion, velocity and acceleration of an object works in opposite direction. and
. Then, the angle between and is At the top of the trajectory of a projectile, the direction of its velocity and acceleration are A ball is thrown at an angle and another ball is thrown at an angle with the horizontal direction from the same point with velocity . The second ball reaches higher than the first ball. Find their individual heights. Take . Assertion: The drover in a vehicle moving with a constant speed on a straight road is in a non-inertial frame of reference.
Reason: A reference frame in which Newton's laws of motion are applicable is non-inertial.
