Q1. A helicopter is ascending vertically with a speed of 8.5 m/s. At a height of 145m above the Earth, a package is dropped from a window. How much time does it take for the package to reach ground?

Q2. A car travelling at 105 strikes a tree. The front end of the car compresses and the driver comes to rest after travelling 0.85. What was the magnitude of an average acceleration of the driver during the collision? State the answer in terms of "'s," where 1.00 = 9.80.

Q3. A 0.525 {rm kg} ball starts from rest and rolls down a hill with uniform acceleration, travelling 155 {rm m} during the second 10{rm s} of its motion.
