A swallow is sitting on a tree branch a certain height above the ground and decides to fly away. Its height (in meters) above the ground can be modeled by the function h(t) = – 2t + 5t + 65, where t is | elapsed time in seconds after the swallow takes flight. Find the height above the ground of the swallow before taking flight: m Find the height above the ground of the swallow at t = 3.46 seconds: m Find the initial velocity of the swallow: m/s Find the velocity of the swallow at t = 3.46 seconds: m/s Find the initial acceleration of the swallow: m/s? Find the acceleration of the swallow at t = 3.46 seconds: m/s?

Find the height above the ground of the swallow before taking flight:
m
Find the height above the ground of the swallow at t
3.46 seconds:
m
Find the initial velocity of the swallow:
m/s
Find the velocity of the swallow at t = 3.46 seconds:
m/s
Find the initial acceleration of the swallow:
m/s?
Find the acceleration of the swallow at t = 3.46 seconds:
m/s?
