Freefall and Projectiles

Question 1

Time to freefall from a height h

Answer 1

t = sqrt(2h/g)

Question 2

Time of flight of a projectile

Answer 2

t = 2(v_y)/g

Question 3

Max height of a projectile

Answer 3

h = (v_y)^2/(2g)

Question 4

Horizontal range on a flat surface

Answer 4

x = (v^2)(sin(2 theta))/(g)
