PEARSON PHYSICS PG 66, #27 Built in Ontario, the world fastest fire truck, the Hawaiian Eagle, can accelerate at 9. 85 m/s². Starting from rest, how long will it take the Hawaiian Eagle to travel a displacement of 402 m?

PEARSON PHYSICS PG 66, #36 A circus performer can land safely on the ground at speeds of up to 13. 5 m/s. What is the greatest height from which the performer can fall?

PEARSON PHYSICS PG 114 #15 An alligator wishes to swim directly North across a channel 500 m wide. There is a current of 2. 0 m/s flowing east. The alligator is capable of swimming at 4. 0 m/s. Find … � The angle at which the alligator must point its body in order to swim directly across � Its velocity relative to the ground � The time it takes to cross.

PEARSON PHYSICS PG 114 #2 Determine the x and y components of the displacement vector 55 m [222º]

PEARSON PHYSICS PG 114 #10 A golf ball is hit with an initial velocity of 30. 0 m/s [55º] what are the ball’s range and maximum height?
