Answer:
A. 33.77 m/s
B. 6.20 s
Explanation:
Frame of reference:
Gravity g=-9.8 m/s^2; Initial position (roof) y=0; Final Position street y= -21 m
Initial velocity upwards v= 27 m/s
Part A. Using kinematics expression for velocities and distance:
Part B. Using Kinematics expression for distance, time and initial velocity
Since it is a second order equation for time, we solved it with a calculator. We pick the positive solution.
