I am currently working through tutorial questions on 'Equations of Motion' and as I struggled with this topic at higher I am still finding such questions challenging and difficult and with no answers for me to work back from, I am very STUCK!! If anyone could help me with the question below I would very much appreciate a work-through solution from which i could not only see how to do it but compare with what i have got so far:

Q: A projectile is launched from the top of a building with an initial speed of 20m/s at an angle of 30 degrees to the horizontal. The height of the building is 30m.

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 velocity).

Thank you. xxx :)
