My son is just starting his advanced highers physics and asks on how best to approach/solve this problem:
A projectile is launched from the top of a building with an initial speed of 20 m s-1 at an angle of 30° to the horizontal. The height of the building is 30 m.
(a) Calculate how long it takes the projectile to reach the ground.
(b) Calculate the velocity of the projectile on impact with the ground, (magnitude and direction).
Appreciate any help.
TIA
