A firework is projected from the level ground in such a way that v0y = 10m/s and v0x = 20 m/s. a) Find the time it takes the firework to reach its maximum height reached. b) Since the firework returns to the ground, it has the same initial and final height. When this happens, the time it takes the object to land is twice the time it takes to reach its maximum height. Using this information, find the horizontal and vertical components of the velocity of the firework right as it lands.

Question
A firework is projected from the level ground in such a way that v0y = 10m/s and v0x = 20 m/s.
a) Find the time it takes the firework to reach its maximum height reached.
b) Since the firework returns to the ground, it has the same initial and final height. When
this happens, the time it takes the object to land is twice the time it takes to reach its maximum height. Using this information, find the horizontal and vertical components of the velocity of the firework right as it lands.
