An astronaut takes a ball and a spring-loaded launch unit to a far away planet to study projectile motions on the planet's surface. The gravitational acceleration on the planet's surface is about 2.4 times less than that of the Earth's surface. Choose all that are correct from the following if the launch angle and launch velocity on the planet's surface are the same as those on the Earth's surface.

NOTE: More than one answer may be correct. You will receive a partial credit for every correct answer and 1/4 points off for every incorrect answer.

The range will be about 2.4 times longer on the planet's surface.

It takes 2.4 times longer to reach the maximum height.

The range will be 6 times longer on the planet's surface.

The range on the planet's surface will be the same as that on the Earth's surface.

The ball will stay above the surface 12 times longer on the planet than on the Earth.

The time it takes to reach the maximum height is the same as that observed on the Earth's surface.

    THE EXPERIMENT The speed "." of a ball as it leaves the spring gun will be measured by projecting the ball horizontally (0-0) from a table top at a distance H above the floor. The gun is then elevated at a known angle 8. The position of the target is calculated using the measured value of v. calculated time of flight, and the equations of motion. A successful prediction with the projectile hitting the target means that the following concepts...

    Newton’s Cannon Imagine you fired a cannonball such that the range of that ball was slightly longer than the radius of the Earth. As that ball fell back down, it would miss the ground and continue to fall. If we can ignore any air resistance or collisions with other objects, then we can say the ball would continue to fall forever, just missing the ground, and thus be in orbit. Assume all orbits here are perfectly circular and pretend that...
