Physics

On planet Jerousek, which has almost no atmosphere, theacceration due to gravity is 10.5 m/s2m/s2.A projectile is launchedfrom the top of a steep hill with an initial velocity of 30 m/s atan angle of 43º from the horizon. The projectile takes 14 s to hitthe ground at the bottom of the hill. (Neglect air resistance)

Part A - How long does it take for the projectile to reach theground?

t =

nothing

s

Part B - What is the y-component of the projectile's initialvelocity?

v0yv0y =

nothing

m/s

Part C - How tall is the hill?

h =
