oh my bad, forgot about that. Thanks so much.
A crate of supplies for a scientific expedition to Greenland is being dropped by plane. When the supplies are dropped, the plane is travelling at 40 m/s horizontally at a height of 50 m. Sadly the parachute fails to open and the package falls to the ground at 9.8 m/s^2. Find the horizontal distance travelled by the package as it falls given that it hits the ground right at the feet of the scientific party.
How do you guys know all this stuff? You haven't even started learning HSC content yet!

The best way to predict the future is to create it
Revised answer if I didn't make any more algebraic mistakes.
Edit: The value with the + (first one) should be omitted as the value of T will be negative. I.e the sound will take longer to reach her from the bottom of the well than the time it takes for the stone to fall and the sound to reach her(?!), which is impossible.

A stone is thrown vertically upwards with a velocity of 29.4 m/s from the edge of a cliff 78.4 m high. The stone falls so that it just misses the edge of the cliff and falls to the ground at the foot of the cliff. Determine the time taken by the stone to reach the ground. Assume that the acceleration due to gravity is 9.8 ms-2

Determine the gravitational force between a 77.5 kg astronaut and Earth when he is standing on the ground. Calculate the change in gravitational force when the astronaut is inside a satellite orbiting the Earth at an altitude of 685 km. The radius of the Earth is 6380 km and the mass of the earth is 5.97*10^24 kg. [4 marks]
