Academics

Q1. A helicopter is ascending vertically with a speed of 4.50 m/s. At a height of 195 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground?

Q2. A motorist travelling at 13 m/s encounters a deer in the road 47 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -5 m/s^2, what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer? Respond in units of s.
