QUESTION 7 Mission Impossible: Special agent Ethan Hunt tries to escape an assassin by jumping horizontally off a flat roof. His goal is to reach a window, two stories or 5.13 m down, on the building across the alley. Ignore air resistance. If the alley is 10.5 m wide, how fast must he run when jumping off the roof?

Answer 1

Question 7 Initial velocity is zero. So, we have, -5.13 0-Lx9.8xt 2x5.13 9.8 t 1.047s Therefore, the required velocity is, 10.5 1.047 v-10.028 m/s
