Answer #1

At the highest point only the vertical component of the velocity is zero. The horizontal component remains unchanged during the flight (neglecting air resistance) . So the given statement is false. The speed of the projectile is non zero at the highest point

True. Since the time of flight depends on the vertical component of the velocity which is countered by the acceleration due to gravity, the time taken will be longer on moon since the gravitational pull of the moon is 1/6th that of Earth's.

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. The same projectile was then fired in the same way toward a wall that is a horizontal distance (d) m from where the projectile was fired, and the projectile (as it's going down) hit the wall. If the wall were slightly farther from where the projectile was launched (the projectile...

A projectile (Object A) sits just on the edge of a 1.500 m high ledge. Its target (Object B) sits at rest directly below it. Object A is launched into the air with an acceleration of 3.000 m/s2 at an angle of 30o above the horizontal. After 1.000~s, Object A is in free fall. At the same moment the projectile is launched into the air, Object B starts moving from rest on the ground in the same general direction as...
