PLEASE SOLVE ALL THE 4 SUBPARTS. I WILL UPVOTEFOR SURE!!
Robin Hood shoots an arrow while standing on the side of a cliffthat is 70m above the sea. The arrow gains height at a constantrate of 10 meters every 3 seconds until it reaches a height of100m. The arrow's trajectory then immediately switches to fallingat a constant rate of 2 meters every second until it lands in thesea.
1. Graph the height of the arrow from the sea with respect totime.
2. Due to the arrow's movement, the flight path of the arrow canbe described by two equations. Determine both equations, describingwhich equation represents each portion of the arrow'sflight.
3. How long does it take for the arrow to land in thesea?
4. Suppose Robin Hood instead shot the arrow at the same angleand with the same strength, but from a boat 1 meter above sealevel. How long does it take for the arrow to land in the sea if itis shot from the boat
